This review introduced the anti-tumor effects of non-steroid anti-inflammatory drugs (NSAIDs) and summarized their possible molecular mechanisms according to recent abroad literatures and our research results. Some evidence showed that the anti-tumor mechanisms of NSAIDs were different in various tumors.NSAIDs decreased the biosynthesis of PGE_2 and regulated the expressions of downstream correlated genes and proteins through restraining abnormal expression of COX-2 in certain neoplasms,which resulted in the inhibition of tumor angiogenesis and proliferation as well as induced apoptosis. But in other cancer cells, NSAIDs, as activators of peroxisome proliferator-activated receptor ? (PPAR?), induced COX-2 expression, promoted the biosynthesis of cyclopentenone prostaglandins (cyPGs). cyPGs further induced tumor cell apoptosis with PPAR? dependently or PPAR? independently. Since their special mechanisms of anti-proliferation and pro-apoptosis, NSAIDs revealed significant synergistic effects with other anti-tumor treatments.

The leading cause of drug withdrawal from market and clinical trials failure is drug-induced liver injury (DILI). Varying clinical, histological and laboratory features of DILI, as well as undefined underlying mechanisms, hinder patients to be diagnosed in the early-stage of the disease and receive effective treatments. Conventional indicators, like serum transaminases and bilirubin, have inevitable limitations referring to sensitive prediction and specific detection of DILI. In order to reduce the occurrence of DILI, researchers have attempted to discover potential biomarkers with higher specificity and sensitivity from blood and urine in recent years. This article aims to review recent advances in biomarkers of DILI.

Objective To investigate the correlation between RDW and disease activity in patients with IBD and evaluate clinical significance of RDW as a potential indicator to monitor IBD activity. Methods 256 patients with IBD were divided into two groups. One was UC group including 136 patients with 80 active period cases and 56 emission period cases. Another was CD group including 120 patients with 75 active period cases and 45 emission period cases. 60 bacillary dysentery diseases and 80 healthy controls were selected as bacillary dysentery group and healthy control group. RDW, Hb, WBC, PLT, CRP, ESR, MCV were tested and monitored with development of disease at different stages. We compared RDW with CRP,ESR, PLT, Hb, MCV parameters. By ROC curve analysis, the sensitivity and specificity of RDW was estimated in identifying the IBD's activity. Results The mean values of RDW in active UC group, remission UC group, bacillary dysentery group and control group were ( 16. 1 ± 2. 7), ( 13.5 ± 2. 1 ), ( 13.0 ± 2. 0)and ( 12. 8 ± 1.8), respectively. There was significant difference among four groups ( F = 51.9, P < 0. 01 ).RDW in active UC group was significant higher than that in remission UC group, bacillary dysentery group and healthy control group ( t = 8. 12, 9. 67, 11.85, P < 0.05) and RDW in remission UC group was significant higher than that in bacillary dysentery group and healthy control group as well ( t = 2. 45, 2. 67,P <0. 05). The mean values of RDW in active CD group, remissive CD group,bacillary dysentery group and control group were ( 16. 9 ± 2. 2 ), ( 13. 8 ± 1.1 ), ( 13.0 ± 2. 0), ( 12. 8 ± 1.8 ). There was significant difference among four groups ( F = 113.9, P < 0. 01 ). RDW in the active CD group was significant higher than that in remission CD group, bacillary dysentery group and healthy control group (t = 11.47,18.63,18. 72, P < 0. 05 ) and RDW in remission CD group was also significant higher than that in bacillary dysentery group and healthy control group ( t = 3.60, 3. 72, P < 0. 05 ). RDW in UC and CD groups demonstrated a positive correlation with CRP and ESR (r=0. 484, 0. 525, 0. 286, 0. 358 and P<0. 01, <0. 01, < 0. 05, < 0. 01, respectively) but an inverse correlation with Hb and MCV (r = -0. 378, -0. 271,- 0. 329, - 0. 298 and P < 0. 01, < 0. 01, < 0. 05, < 0. 01, respectively). In UC groups RDW represented a larger area under ROC curve (0. 8.54) compared with CRP, ESR, PLT, Fib and MCV. When the cut-off value of RDW was 14. 0, the sensitivity and specificity for identifying active UC were 82% (65/80) and 72% (40/56) respectively. In CD groups, the area of RDW under ROC curve was the largest (0. 925 )among all indicators. When the cut-off of RDW was 14.5, the sensitivity and specificity for identifying active CD was 88% (66/75) and 82% (37/45) respectively. Conclusion RDW in patients with IBD is a useful indicator to estimate the IBD activity and predict disease progression.

Objective To investigate the expression and significance of B lymphocyte stimulator (Blys) and its receptor BAFF (BAFF-R) in peripheral blood mononuclear cells (PBMCs) from patients with systemic lupus erythematosus (SLE). Methods The expression of Blys and BAFF-R was measured by flow cytometry in 90 pa-tients with SLE,which was compared with that of 45 healthy controls. The relationships between the expression of Blys, BAFF-R and other laboratory parameters as well as disease activity were analyzed. Results The expression of Blys and BAFF-R in PBMCs from patients with SLE was significantly elevated compared to healthy controls (P <0.001), so did the active group (P < 0.001) and inactive group (P < 0.001 and P < 0.01). The expression of Blys in PBMCs from active SLE patients was higher than that of inactive patients (P <0.05). However,there was no statisti-cal difference of BAFF-R between the two groups. The expression of Blys in PBMCs was positively related to SLEDAI (r =0.728,P <0.001) ,IgG and IgM(r=0.691,P<0.001 and r =0.453,P<0.01) ,but negatively related to C3 and CA (r = -0.510, P < 0.001 and r = -0.312, P < 0.05). The expression of Blys in dsDNA positive group was higher than those of dsDNA negative group (P < 0.01). The expression of Blys and BAFF-R in Cl qAb positive group was higher than those of ClqAb negative group as well (P <0.01). Conclusion The expression of Blys and its receptor BAFF-R in PBMCs from SLE is elevated ,which may reflect the disease activity and is related to the pro-duction of autoantibody. They might be involved in the pathogenesis of SLE.

Objective To investigate the risk factors of disease progression and adverse pregnancy outcome in patients with systemic lupus erythematosus (SLE) during pregnancy.Methods Clinical data of 118 pregnant women with SLE admitted from June 2004 to October 2015 were retrospectively analyzed.The patients were divided into selective pregnant group (group A,n =72 cases) and non-selective pregnant group (group B,n =46) according to the disease activity of SLE.The disease progression and pregnancy outcomes were compared between two groups.Results The various system damages occurred in group B,including hematological damage in 16 cases,kidney damage in 19 cases,erythra in 10 cases,arthritis in 10 and serositis in 12 cases;while the corresponding cases in group A were 10,14,6,4 and 4(x2 =7.133,P=0.008;x2 =6.658,P =0.010;x2 =4.304,P =0.038;x2 =7.030,P =0.008;x2 =10.095,P =0.001).SLE exacerbation occurred in 28 cases (74％) of group B and 12 cases (17％) of group A (x2 =34.944,P =0.000).The logistic regression analysis showed that hypocomplementemia,proteinuria,SLEDAI score before pregnancy and positive anti-dsDNA antibody were the risk factors of SLE disease exacerbation during pregnancy.The maternal complications occurred in group B,including pregnancyinduced hypertension in 7 cases,preeclampsia in 10 cases and infections in 11 cases/times;while the corresponding cases (case/time) in group A were 2,6 and 4 (x2 =4.526,P =0.033;x2 =4.304,P =0.038;x2 =8.525,P =0.004).There were 14 cases of therapeutic induced labor,7 case of stillbirth and 27 cases of total fetal loss in group B,while the corresponding cases in group A were 2,0 and 4 (x2=18.317,P =0.000;x2 =9.080,P =0.003;x2 =40.920,P =0.0300).The logistic regression analysis showed that positive anticardiolipin antibody,proteinuria,SLEDAI score before pregnancy and renal dysfunction during pregnancy were risk factors of fetal loss.There were 87 cases of successful delivery (73.7％),the successful delivery rates were 41.3％ (19/46) in group B and 94.4％ (68/72) from group A,respectively.The infant complications occurred in group B,including premature birth in 15 cases,low birth weight in 13 cases,neonatal jaundice in 5 cases and mild asphyxia in 5 cases;while the corresponding cases in group A were 24,18,4 and 2 (x2 =11.442,P =0.001;x2 =11.395,P =0.001;x2 =4.664,P =0.031;x2 =8.035,P =0.005).Conclusion SLE patients whose disease conditions are not well controlled would lead to higher percentage of disease deterioration during pregnancy and worse pregnancy outcomes.

Objective To investigate the significance and distribution of lymphopenia and antilymphocyte antibody(ALA) in systemic lupus erythematosus (SLE) and to explore the role of ALA in lympho penia.Methods One hundred and ten in-patients who were admitted during February 2003 to February 2008 were retrospectively reviewed.Indirect immunofluorescence test was used to detect ALA.Results ① Lymphopenia (＜1.5×109/L) was observed in 68.2% patients.Lymphopenia was associated with skin rashes,serositis,renal involvement,NPSLE,leucopenia,ANA,ds-DNA antibody,ESR and IgG levels.The lymphocyte count and SLEDAI scores was more closely correlated than total white blood cell counts.②ALA was positive in 51/110 (46.4%) patients.ALA was associated with renal involvement,NPSLE,WBC count,C3 level decrease,ANA,dsDNA antibody and SLEDAI scores.Conclusion Lymphopenia is significantly associated with SLEDAI scores.ALA is possibly one cause of lymphcytopenia.In addition,ALA is also a parameter for disease activity,and is associated with organ involvement and outcomes.

BACKGROUND: Direct anterior minimum invasive surgery (DAMIS) total hip arthroplasty has been considered as the total hip arthroplasty that is most consistent with the minimally invasive standards. In theory, there is a low incidence of complications in the DAMIS total hip arthroplasty. However, because minimally invasive surgery demands high surgery skills, the incidence rate of complications is high in the early period of its learning curve. Lateral decubitus position DAMIS was considered to provide a better perspective, so that, the incidence of surgical complications may be reduced. OBJECTIVE: To explore the feasibility of lateral decubitus position DAMIS for total hip arthroplasty. METHODS: Totally 62 cases from the Department of Orthopedics, First Affiliated Hospital of Gannan Medical University between April 2013 and April 2016 were retrospectively analyzed, and randomly assigned to two groups: lateral decubitus position group (n=31) and supine position group (n=31). Incision length, operative time, intraoperative blood loss, acetabular cup angle, hospital stay, Harris scores, Visual Analogue Scale score, and SF-36 score were compared between the two groups. Complications at postoperative 1 year were recorded. RESULTS AND CONCLUSION: (1) Operative time was longer and intraoperative blood loss was more in the lateral decubitus position group than in the supine position group (P < 0.05). There were no statistically significant differences in incision length and hospital stay between the two groups (P > 0.05). (2) There were no significant differences in the incidence of postoperative complications between the two groups (P >0.05). (3) There were no significant differences in the anteversion and abduction angles of acetabular cup between the two groups (P > 0.05). (4) There were no significant differences in Harris hip score, Visual Analogue Scale score, and SF-36 the quality of life scores between the two groups before surgery and 1 year after surgery (P > 0.05). (5) In conclusion, DAMIS total hip arthroplasty can abandon special traction bed when patients are in lateral decubitus position. The short-term effects are the same with supine DAMIS total hip arthroplasty.
