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.

Pancreatic cancer is a kind of highly malignant aggressive cancers.Perinearal growth is one of the importcant biological characteristics of pancreatic cancer.Perineural invasion is an independent prognostic indicator of its prognosis.However,the mechanism has not yet completely clear.The pancreatic cancer perineural invasion mechanism research has been the focus of scholars to discuss,however it' s difficult to break through.Therefore,the discussion pancreatic violation of the peripancreatic neural mechanism for early clinical find,early treatment is essential.The mechanisms of pancreatic cancer research,from all kinds of adhesion molecule to the nerve growth factor,related ligand protein path to susceptibility gene expression,have been reported largely,which helps enhance people' s awareness of peripancreatic neural invasion.At the same time,perineural invasion in the early detection of disease,prolonging survival period and improving the quality of life has important significance.Now the progresses of reviews in recent years are discussed as follows.

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).

SUMO (small ubiquitin-related modifier) is involved in the post-translational modifications of proteins,and this process is referred to as SUMOylation.SUMOylation plays an important role in the regulation of cellular activities such as strengthening the stability of the protein,nucleocytoplasmic transport,DNA repair,DNA replication,mitotic and meiotic chromosome behavior,et al.SUMOylation is a dynamic process and can be reversed by SUMO-specific proteases (SENP).Once the balance between SUMOylation and de-SUMOylation is broken,there will be an aberrant expression of SUMO or SENPs in cells to happen,which may lead to the tumor occturtrence.

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 To analyze the clinical characteristics of brucellosis presenting as fever of unknown origin in non-endemic area.Methods Clinical data of 11 patients with fever of unknown origin,who were admitted in a general hospital of non-endemic area from Jan 2013 to Jan 2017 and diagnosed as brucellosis by blood culture,were retrospectively analyzed.Results There were 8 males and 3 females aged 40-70 years.The patients were admitted with or without accompanied symptoms.The patients were initially presented in rheumatology (1 case),neurology (1 case),emergency (4 cases),hematology (1 case),orthopedics (2 cases) and pneumology (2 cases) departments,respectively.The time from onset to presentation was 0.5-7.0 months.The clinical manifestations were nonspecific,and blood cultures of Brucella were positive between 2 to 5 weeks with a mean of 3 weeks.Time to diagnosis was 1 to 9 months with a mean of 4 months.All patients were transferred to infectious hospital when the diagnosis was confirmed.The telephone follow-up showed that none of the patients had fever after discharged.Conclusion Brucellosis should not be neglected in the differential diagnosis of FUO in non-endemic area,and blood culture is important for a definitive diagnosis.

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.
