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.

OBJECTIVEFunctional defects in NK cells have been proposed to be responsible for the impairment of anti-tumor immune responses. However, it remained unclear whether the function of NK cells were impaired in patients with hepatocellular carcinoma. To address this issue, we analyzed the frequency and function of peripheral NK cell subsets in hepatocellular carcinoma (HCC) patients.

METHODS35 HCC patients and 24 healthy controls (HC) were enrolled in the study. Peripheral NK frequency was analyzed using flow cytometry. In addition, the capacity of NK cells to produce IFN gamma and to lyse K562 cells was evaluated.

RESULTSIn contrast with the healthy controls, the frequency of peripheral NK cells in hepatocellular carcinoma patients was decreased (12.19%+/-10.85% vs 24.01%+/-8.78%, u = 4.01, probability value less than 0.01), while the frequency of CD56(bright)CD16(neg) NK cells was increased (0.62%+/-0.39% vs 0.48%+/-0.28%, u = 1.96, probability value less than 0.05), and the frequency of CD56(dim)CD16(pos) NK cells was significantly decreased (11.59%+/-7.49% vs 22.66%+/-8.84%, u = 3.92, probability value less than 0.01). In addition, peripheral NK cells from HCC patients exhibited decreased capacity to produce IFN gamma (effective cells 13.31%) and to lyse K562 cells (mixed ratio 30:1, 10:1, 1:1, effective cells 16.72%+/-7.33% vs 26.29%+/-12.36%, u = 2.52, P less than 0.05, 8.01%+/-4.40% vs 13.09%+/-5.03%, u = 3.32, probability value less than 0.05, 3.51%+/-2.82% vs 3.42%+/-1.64%, u = 1.56, probability value more than 0.05, respectively) as compared with healthy subjects.

CONCLUSIONAnti-tumor activity of NK cells in HCC patients was impaired.

OBJECTIVETo compare the therapeutic effects of debris spondylectomy, piecemeal spondylectomy, total en bloc spomdylectomy in treating lumbar metastatic tumors.

METHODSThe clinical data of 20 patients with lumbar metastatic tumors treated from January 2008 to October 2013 were retrospectively reviewed. There were 8 males and 12 females, aged from 35 to 65 years old with an average of (49.50 ± 9.97) years. All patients had single solitary metastases. Four cases were in L1,5 cases in L2,4 cases in L3,4 cases in L4, and 3 cases in L5. According to the type of Tomita, type II had in 4 cases, type III in 6 cases, type IV in 6 cases, type V in 4 cases. Tokuhashi score was 12.50 ± 1.97. All patients complained with back or leg pain, VAS score was 8.13 ± 0.85. Among patients, 7 cases were treated with debris spondylectomy (group A), 7 cases with piecemeal spondylectomy (group B), 6 cases with total en bloc spondylectomy (group C). Statistical analysis was used to compare the three groups with respect to surgical trauma (including operative time, transoperative bleeding, and intraoperative blood transfusion), clinical symptoms (by VAS score at 1 week after operation), surgical procedures conditions (by AP and lateral X-rays), and long-term results (by recurrence and death information).

RESULTSAll patients were followed up from 6 to 36 months with an average of (16.50 ± 7.88) months. Operative time for debris spondylectomy was (6.14 ± 0.68) h, intraoperative bleeding was (3 457.14 ± 399.40) ml, and intraoperative blood transfusion was (2 771.43 ± 423.14) ml. Operative time for piece-meal spondylectomy was (4.93 ± 0.61) h, intraoperative bleeding was (1 942.86 ± 378.51) ml, and intraoperative blood transfusion was (1 500.00 ± 336.65) ml. Operative time for total en bloc spondylectomy was(4.17 ± 0.67) h, intraoperative bleeding was (1 341.67 ± 361.13) ml, and intraoperative blood transfusion was (916.67 ± 321.66) ml. There was significant differences in operative time, intraoperative blood loss, and intraoperative blood transfusion between three groups (P < 0.05). In terms of these factors, total en bloc spondylectomy had the best outcome followed by piecemeal spondylectomy. All pains had released, VAS score decreased obviously at 1 week after operation (P < 0.05), and there was no significant differences between three groups (P > 0.05). Surgical effects were well with these methods according to the evaluation of AP and lateral X-rays . At final follow-up, group A had 4 recurrences (2 with breast cancer, 1 with prostate cancer,and 1 with thyroid cancer) and 3 deaths (2 with lung cancer and 1 with thyroid cancer); group B had 2 recurrences (1 with breast cancer and 1 with prostate cancer) and 3 deaths (1 with lung cancer, 1 with breast cancer and 1 with kidney cancer);group C had no recurrences and 2 deaths for lung cancer. There was significant differences in recurrence and death between three groups (P < 0.05). In terms of these factors, total en bloc spondylectomy had the best outcome in three methods.

CONCLUSIONThree kinds of operation method can relieve pain, improve nerve function, increase the spinal stability, control the local lesions, improve the patient's quality of life in treating lumbar metastatic tumors, but total en bloc spendylectomy, respect to operative time, transoperative bleeding, intraoperative blood transfusion, tumor recurrence and death is clearly superior to other two methods.

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.
