Objective　To investigate the mechanism affecting on permeability of vascular endothelial cell by nitric oxide (NO). Methods　Series concentration of sin-1（a donor of NO） were added to ECV 304, a cell line of human umbilical vein endothelium. Cell growth and expression of f-actin, a cytoskeleton protein were observed. Results　Cell growth was inhibited with a dose from 6.25 to 100 μmol/L and was caused to death at the concentration of 50 to 100 μmol/L by sin-1. The expression of f-actin was suppressed obviously after cultured with 100 μmol/L sin-1 for 4 hours. Conclusion　It suggests that anomaly increased NO can increase permeability of blood vessels by suppressing the expression of f-actin, inhibiting cell growth or even resulting in cell death.

Objective To investigate and evaluate the clinical value of full endoscopic transnasal transphenoidal approach for the surgery of pituitary adenomas.Methods Seventy-two patients,who underwent full endoscopic transnasal transphenoidal approach for the surgery of pituitary adenomas,were selected from the Medical Center of Pituitary Adenomas of our hospital from January 2009 to March 2012.To retrospectively investigate pre- and post-operation symptoms,hormone levels,images information,operation information,complications,following-up information and so on.Results Among the 72 consecutive patients,there were 22 nonfunctioning adenomas,twenty-four prolactin secreting adenomas,seven somatotropin secreting adenomas,five adrenocorticotropic hormone secreting adenomas,one thyrotropin secreting adenomas,and 13 multi-secreting adenomas.The tumor removal was total in 56(77.8％),subtotal 13(18.0％),and partial 3(4.2％).Five cases had CSF leaks,and 6 diabetes insipidus.After 3-24 months of follow-up,the levels of increasing-hormone declined to normal levels in most patients.Conclusion Full endoscopic transnasal transphenoidal approach for the surgery of pituitary adenomas is a kind of technique which is safe,minimally invasive,having less complications and fast recovery.However,it is necessary for surgeons to accept systematic and specialized training,and own advanced equipments.

OBJECTIVETo prepare the polyclonal antibody of human endothelial-overexpressed lipopolysaccharide-associated factor 1 (EOLA1), and to determine the expression of EOLA1 in human umbilical vein endothelial cell (HUVEC).

METHODSThe protein samples (sample 1 and 2) expressing EOLA1 were purified and renatured. The protein concentrations were determined with bicinchoninic acid assay. The protein samples were identified with peptide mass fingerprinting (PMF) analysis. Protein sample with higher coincidence rate of amino acid sequence with theoretic protein was used to inoculate 4 mice; another 4 mice inoculated with adjuvant were used as control. Serum was isolated from collected mice blood. Polyclonal antibody of EOLA1 was purified with saturated ammonium sulfate precipitation, and was determined with ELISA for the titer (data were denoted by absorbance value). The expression of EOLA1 in HUVEC was determined with Western blot.

RESULTSThe concentration of protein sample 1 and 2 was respectively 0.124 16 mg/mL and 0.132 15 mg/mL. According to PMF analysis, the coincidence rate of amino acid sequence between protein samples and theoretic protein were 32% (protein sample 1) and 24% (protein sample 2). The polyclonal antibody of EOLA1 with titer more than 1:10 000 was obtained from mice inoculated with protein sample 1. The expression of EOLA1 protein in HUVEC was determined with polyclonal antibody of EOLA1.

CONCLUSIONSThe polyclonal antibody of EOLA1 can be prepared by inoculating mice with EOLA1 prokaryotic expressing protein, which can be used for determination of EOLA1 protein.

OBJECTIVETo investigate the possibility of subjective rate, primary task evaluation and psychophysiology evaluation as methods for mental workload assessment of mental arithmetic on visual display terminal (VDT).

METHODSThe indexes including Cooper-Harper scale score, correct rate, speed in answering questions, heart rate variability, pupil size and blink rate were recorded during the performance of three different difficult tasks.

RESULTSWith the variable number of formula increasing, the Cooper-Harper scale score increased, the right rate decreased, the speed decreased, pupil size increased, and blink rate significantly decreased. In comparison with rest, the value of TP, VLF, LF, LFnorm, LF/HF decreased remarkably in the mental arithmetic task, the value of HFnorm, HF/TP, rMSSD increased. However, the difference was not significant among three groups.

CONCLUSIONWith the variable number of formula increasing, the participant's mental workload increases. Every method of mental workload evaluation can assess the mental workload information for three tasks at various different levels in a way. Multi-indexes may be appropriate for mental load assessment.

Abstract: Our previous work revealed berberine can significantly enhance the susceptibility of fluconazole against fluconazole-resistant Candida albicans, which suggested that berberine has synergistic antifungal activity with fluconazole. Preliminary SAR of berberine needs to be studied for the possibility of investigating its target and SAR, improving its drug-likeness, and exploring new scaffold. In this work, 13-substitutited benzyl berberine derivatives and N-benzyl isoquinoline analogues were synthesized and characterized by 1H NMR and MS. Their synergetic activity with fluconazole against fluconazole-resistant Candida albicans was evaluated in vitro. The 13-substitutited benzyl berberine derivatives 1a-1e exhibited comparable activity to berberine, which suggested that the introduction of functional groups to C-13 can maintain its activity. The N-benzyl isoquinolines, which were designed as analogues of berberine with its D ring opened, exhibited lower activity than berberine. However, compound 2b, 2c, and 4b showed moderate activity, which indicated that berberine may be deconstructed to new scaffold with synergistic antifungal activity with fluconazole. The results of our research may be helpful to the SAR studies on its other biological activities.

OBJECTIVETo explore the effect of Changji'an Capsule (CA) on mRNA expressions of neuropeptide Y (NPY) in the hypothalamus and colon and serum levels of adreno-cortico-tropic hormone (ACTH) in rats of diarrhea predominant irritable bowel syndrome (IBS-D) model rats.

METHODSTotally 48 SD rats were randomly divided into six groups, i.e., the normal control group, the model group, the Pinaverium Bromide group (PB, 0.018 g/kg), the high dose CA group (2.812 g/kg), the medium dose CA group (1.406 g/kg), and the low dose CA group (0.703 g/kg), 8 in each group. The IBS-D rat model was established by using separation of breast milk + stimulation of acetic acid + constraint of four limbs. Normal saline was given to rats in the normal control group and the model group. All medication lasted for 14 successive days by gastrogavage. The serum content of ACTH was detected by enzyme linked immunosorbent assay (ELISA). The expressions of NPY mRNA in the colon and the hypothalamus were detected using real-time fluorescence quantitative PCR.

RESULTSCompared with the normal control group, the serum ACTH content significantly increased (P < 0.01), the NPY mRNA expression in the colon and the hypothalamus obviously decreased (P < 0.01) in the model control group. Compared with the model group, the serum ACTH obviously decreased in the high dose CA group, the medium dose CA group, and the PB group (P < 0.01, P < 0.05). The NPY mRNA expression in the colon and the hypothalamus were obviously up-regulated in the high dose CA group, the medium dose CA group, the low dose CA group, and the PB group (P < 0.05).

CONCLUSIONSCA could modulate the abnormity of brain-gut axis of IBS-D rats possibly by up-regulating NPY mRNA expressions in the hypothalamus and the colon and down-regulating the ACTH content in the hypothalamic-pituitary-adrenal axis.
