Objective To investigate the effect of tonic pain stimulation on the attention network test (ANT) . Methods Twenty healthy males recruited from university were enrolled in this study, and laboratory pain was induced by cuff pressure stimulation on the upper arm. All subjects performed the task separately under pain, no-pain and pressure conditions. The reaction time and accuracy rate of the ANT were quantified. The subjective pain perception was assessed by the short-form McGill Pain Questionnaire ( SF-MPQ) . Results Across three conditions, the executive network showed significant pain effect (F = 76.31 , P< 0.001) : no-pain condition at (92.51 ±35.71 )ms, pressure condition at (94.06 ±25. 28) ms, pain condition at ( 120.24 ± 18.21 )ms. Furthermore, the average reaction time and the A-scores (i. e. affective words) in SF-MPQ caused by pain was positively correlated ( r = 0.11, P = 0.03) . Conclusion Pain can result in deficit in the executive network for attention regulation. The negative affections caused by pain can interfere with attention.

AIM: To study the effects of oxidized high-density lipoprotein (oxHDL) on the expression of monocyte chemoattractant protein-1(MCP-1) and intercellular adhesion molecule-1(ICAM-1) and intracellular free calcium concentration （［Ca2＋］i） level in cultured human umbilical venous endothelial cells(HUVECs). METHODS: The MCP-1 protein content in the medium of conditioned HUVEC was measured by ELISA, and the ICAM-1 on HUVECs was detected by indirect immunofluorescence, and ［Ca2＋］i was determined by Fluo-3/AM, the injury of cells was observed by scanning electron microscopy (SEM).RESULTS: oxHDL could induce the expression of MCP-1 and ICAM-1 in HUVECs. In oxHDL group (HUVECs were incubated with 100 mg protein/L oxHDL for 24 h), the levels of MCP-1, ICAM-1 and ［Ca2＋］i increased by 160%, 60% and 70% respectively compared with the control group (P＜0.01). When HUVECs were incubated with 300 mg protein/L oxHDL for 24 h, cells were injured obviously. CONCLUSION: By inducing the expression of ICAM-1 and MCP-1 in endothelial cells, oxHDL may promote monocyte-endothelium adhesion and monocyte migration to intima, it may promote atherosclerosis as oxidized low-density lipoprotein (oxLDL).

Objective To evaluate the effect and safety of transobturator inside-out tension-free urethral suspension (TVT-O) as the surgical treatment on post-operational recurrence of female stress urinary incontinence (SUI). Methods Eleven women with SUI recurrence who underwent TVT-O were selected in the research. Their incontinence recurred from 1 months to 8 years after the previous surgical treatment.Results The operative time was (28 ±9) min, the bleeding volume was (15 ±5) ml. Postoperative complications: urinary retention in 1 case, vaginal erosion in 1 case. Follow-up was enforced for 6-36months, median time was 16 months. Grouts-Blaivas analogue scale:among the 11 patients, 9 patients were cured, 2 patients were improved. ICI-Q-SF score: preoperative 13-21 ( 15.36 ± 2.34) scores compared to postoperative 0-9 (1.46 ±3.27) scores (t =5.850,P ＜0.01 ). I-QOL score: preoperative 23.33-36.67(29.85 ± 4.74) scores compared to postoperative 66.67-100.00 (95.15 ± 10.12) scores (t = 17.753,P ＜0.01 ). PISQ-12 score of 10 patients: preoperative 16-25 (20.10 ± 3.07) scores compared to postoperative 11-20( 14.00 ± 2.83 ) scores (t = 11.600, P ＜ 0.01 ). Conclusion If conservative treatments fail, TVT-O is highly effective and safe for the postoperative recurrent SUI.

Objective To investigate the relationship of the serum anti-lysosome associated membrane protein 2 (LAMP-2) antibody levels and anti-neutrophil cytoplasmic antibodies (ANCA)-associated glomerulonephritis.Methods Thirty-three patients with new onset ANCA-associated glomerulonephritis and thirty healthy controls were enrolled.ANCA detection was performed using indirect immunofluorescence (IIF).Enzyme-linked immunosorbent assay (ELISA) was used to detect myeloperoxidase (MPO),proteinase-3 (PR3) and other ANCA-associated antibodies including LAMP-2.The cut-off value of the serum anti-LAMP-2 antibody was determined by a receiver operating characteristic (ROC) curve.Results The serum levels of anti-LAMP-2 antibody in new onset ANCA-associated glomerulonephritis patients were significantly higher than remission stage ANCA-associated glomerulonephritis patients and healthy controls (P ＜ 0.05).The serum levels of anti-LAMP-2 antibody showed no visible difference between the remission ANCA-associated glomerulonephritis patients and healthy controls (P ＞ 0.05).The levels of anti-LAMP-2 antibody showed a strong positive correlation with ESR,Scr,BUN,proteinuria,crescent proportion and Birmingham vasculitis activity score (BVAS) and a negative correlation with Ccr,Hb and Alb.Conclusions Anti-LAMP-2 antibody is correlated with the activity of ANCA-associated glomerulonephritis and the severity of renal damage.It may be a useful indicator on the activity of ANCA-associated glomerulonephritis.

Objective Liver is a common site of metastasis of gastric cancer and hitherto there has been no uniform treatment for liver metastasis of gastric cancer. This study was to investigate the clinical characteristics and prognostic factors of liver metastasis of gastric cancer in order to provide some evidence for the improvement of the diagnosis and treatment of the disease. Methods We ret-rospectively analyzed the clinical characteristics and survival data of 143 patients with liver metastasis of gastric cancer treated in our hospital between March 2007 and September 2012. We investigated the independent risk factors affecting the prognosis of the disease u-sing the Cox Regression Model. Results Seventy-five ( 52. 4%) of the 143 patients survived for 12 months, 41 ( 28. 7%) for 24 months, and 18 (12.6%) for 36 months, with a median survival time of 14 months. Univariate analysis revealed statistically significant differences in the survival time among the patients with different histological grades of primary gastric cancer, time of liver metastasis, types of metastatic liver cancer, extra-liver metastasis, and treatment methods ( P<0.05) . Multivariate Cox regression analysis showed the histological grade of gastric cancer to be low-or non-differentiation ( HR=2.67, 95% CI:1.51-4.72) and the type of liver meta-static cancer to be H2 ( HR=1.89, 95% CI:1.08-3.29) or H3 ( HR=2.13, 95% CI:1.32-3.44) , which were independent risk fac-tors affecting the prognosis of liver metastasis of gastric cancer, while palliative chemotherapy ( HR=0.55, 95% CI:0.32-0.95) was an independent protective factor of its prognosis. Conclusion Patients with liver metastasis from gastric cancer usually have a poor prognosis, especially those with histologically low-grade gastric cancer or type-H2 or -H3 liver metastatic cancer. The prognosis of thepatients undergoing palliative chemotherapy may have a better prognosis than those receiving best supportive care. A comprehensive therapy should be recommended to patients with liver metastasis from gastric cancer.

With the illustration of the L-Arg-NO-cGMP pathway in penile erection,the researches on nitric oxide synthases(NOSs),which produce nitric oxide(NO)as the main messenger to control the process,has stayed in the spotlight.nNOS locates in neuroal tissues and eNOS is binding on the membrane of cavernous sinus endothelium with caveolin.The nNOS & eNOS are expressed constitutively.The activation of nNOS & eNOS is more dependent on Ca2+ concentration than iNOS,which is seldom expressed except in aged or pathological conditions.It is now clear that nNOS may initiate cavernosal tissue relaxation under the regulation of PDZ zone when transcripted,while phosphorylated eNOS may facilitate attainment and maintenance of full erection.iNOS expression stimulated by the cytokines may be beneficial(cytoprotective or anti-fibrotic)or deleterious(cytotoxic)according to the tissue environment.Gene therapies based on NOSs have attained a great deal of achievements in animal experiments and will promise a wonderful future.

OBJECTIVE:To discuss the effects of Rujieping capsule on estrogen receptor(ER) and progesteron receptor(PR) of pathological tissues in rats with hyperplasia of mammary glands.METHODS:The rats were injected i.m with Estradiol benzoate injection for 25 days followed by the injection of Progesterone injection i.m for 5 days to establish the model of hyperplasia of mammary glands.Which were treated with high and low doses of Rujieping capsule respectively for 30 days with tamoxifen as positive control.RESULTS:Both tamoxifen and high and low doses of Rujieping capsules could lessen the symptoms of red swelling of nipples or hyperplasia of mammary glands,lower the levels of E2 and PRL,enhance the level of progestone,lower the index of uterus,markedly reduce the number of layers of the ductal epithelial cells,reduce the levels of ER and PR in mammary glands,and suppress mammoplasia.CONCLUSION:Rujieping capsules is effective in the treatment of hyperplasia of mammary glands in rats by regulating the level of estrogen and improve pathomorphologic change of hyperplastic mammary glands.

[Summary] Long noncoding RNA( lncRNA) plays an important role in regulating the life activities, and its disordered expression is closely related to many diseases. Several studies have shown that lncRNA could modulate the endocrine metabolic processes at transcription, post-transcription, and the epigenetic modification levels, but the exact mechanism is still unclear. Further research needs to be done. This review will briefly describe the research progress of lncRNAs in endocrine and metabolic respects.
