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.

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.

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.

This study was purposed to investigate the efficacy of different whole flow lysis reagents for lysis of red blood cells in flow cytometric analysis. The expression of immunocytes was detected by flow cytometry after lysis of red blood cells using commercial reagents (Optilyse C, FACS Lysing Solution) and self-made red blood cell lysis reagents (RBC Lysis Buffer), the detection results were analyzed comparatively. The results showed that there was no significant difference in the percentage of CD3e(+), CD3e(+)CD4(+), CD3e(+)CD8a(+), CD3e(-)CD19(+), CD3e(-)NK1.1(+) and Gr-1(+) cells between 3 different lysis reagent groups. However OptiLyse C solution was suitable to Gr-1(+) cell detection, but did not suit to Foxp3(+) Treg detection. The self-made RBC Lysis Buffer and FACS Lysing Solution were suited to Foxp3(+) Treg detection. It is concluded that the use of self-made RBC Lysis Buffer for flow cytometry can get the lysis efficiency of commercially available lysis solutions when samples are prepared in accordance with standardized procedure. The self-made RBC Lysis Buffer not only can satisfy experimental requirements, but also can reduce the experimental costs.
