Objective To investigate the clinical value of neutrophil-to-lymphocyte ratio,platelet-to-lymphocyte ratio and red blood cell distribution width in discriminating disease activity of rheumatoid athritis.Methods Eighty-nine rheumatoid arthritis out-patients of the Affiliated Hospital of Jiangsu University from Jan.2012 to Mar.2013 were recruited into this study.The disease activity index,such as swollen joint count and tender joint count were made by rheumatologists,and laboratory parameters（blood cell analysis,erythrocyte sedimentation rate and C-reactive protein) were measured as well.The enrolled patients were divided into the active RA group and remission RA group based on the DAS28 definition.Differences of NLR,PLR and RDW among groups were analyzed by t test and relations between variables were assessed by Spearman correlation analysis.The t test,non-parametric test and Spearman analysis were used for statistical analysis.Results The levels of NLR (3.2±2.0,2.4±0.9,respectively) and PLR (167±70,133±43,respectively) in active RA group were higher than that of the RA remission group (t=2.28 and 2.50,P=0.02 and 0.01).The level of RDW [(13.9±2.5)％,(13.9±2.4)％,respectively] was not significantly different between the active RA group and the RA remission group (t=0.14,P=0.89).However,compared with healthy controls,the level of RDW [(13.9±2.5)％,(13.2±0.2)％,respectively] was significantly increased in RA patients (t=2.74,P=0.006 9).NLR and PLR were positively correlated with DAS28 (r=0.23,P=0.03;r=0.26,P=0.04,respectively),ESR (r=0.28,P=0.03;r=0.43,P＜0.01,respectively) and CRP (r=0.33,P=0.006;r=0.41,P＜0.01,respectively).However,there was no association between RDW and DAS28 (r=0.01,P=0.93),ESR (r=0.20,P=0.15) and CRP (r=0.05,P=0.71).Areas under curve of receiver operating characteristic (ROC) for assessing disease activity of rheumatoid athritis by NLR and PLR were 0.802 and 0.753 respectively.The cut-off values for discriminating active/remission RA were 2.86 and 143.05,with the sensitivity as 0.66 and 0.63,specificity as 0.72 and 0.65.Conclusion NLR and PLR are significantly associated with the disease activity of RA and can be useful to understand the activity state of the illness.

AIM: To observe the direct effects of peripheral blood monocytes/macrophages (MO/MAC) on renal tubular epithelial cells (RTEC),and further probe into the possible mechanisms. METHODS: Conditioned medium(M-CM) of human peripheral blood MO/MAC was collected and added to HK-2,a human renal proximal tubular cell line.After incubation with M-CM for 24 hours,HK-2 cells were detected for DNA synthesis by -TdR incorporation,osteopontin (OPN) and ?-smooth muscle actin (?-SMA) expression by Western blot,and fibronectin(FN) secretion by ELISA.Furthermore,anti-TGF?_1 neutralizing antibody and interlukin-10(IL-10) were used separately to antagonize the effects of M-CM on HK-2 cells. RESULTS: ①DNA synthesis,?-SMA expression and FN secretion were all increased in HK-2 cells when incubated with M-CM.②When adding with anti-TGF?_1 neutralizing antibody (5 mg/L) in the M-CM,the degree of upregulation of ?-SMA and FN in HK-2 cells was much lower than that stimulated by M-CM alone.③M-CM added with IL-10 (20 ?g/L) had a weaker ability to induce the increasing in ?-SMA expression and FN excretion in HK-2 cells, compared with M-CM itself alone.M-CM from MO/MAC preincubated with IL-10 caused a lower upregulation of ?-SMA expression in HK-2 cells than M-CM from non-preincubated MO/MAC. CONCLUSION: MO/MAC can directly induce proliferation,transdifferentiation and extracellular matrix secretion in RTEC.TGF?_1 and proinflammatory cytokines secreted by MO/MAC might be involved in the aboveeffects.

AIM A&A treated PAN rats, and to observe the effects of A&A on MAPK signaling pathway. METHODS Rats were divided into control, PAN, A&A treated PAN (A&A) and enapril treated PAN (ACEI) groups. The pathological lesion was observed under a light microscope. Immunohistochemistry combined with semi quantitive method was used to investigate the following parameters: cell number, ? SMA expression and extracellular matrix deposition. Expression and phosphorylation of protein kinases ERK, JNK and p38 were assayed. RESULTS In PAN rats, A&A suppressed ? SMA expression, which was closely correlated to cell proliferation, and extracellular matrix accumulation in glomerular mesangium. A&A significantly attenuated ? SMA expression in the tubulo interstitial area which was also parallel to the renal interstitial fibrosis.In this study, expression of all subtypes of MAPK had no difference between control and PAN groups. Compared with the inactivation of ERK and p38, phosphorylation of JNK was observed in glomeruli, renal tubules and interstitial cells in PAN rats, which was also inhibited by A&A treatment. CONCLUSION The inhibitory effect of A&A on phenotypic changes of renal resident cells, especially glomerular mesangial cell, may participate in its renal protective mechanisms. This effect, at least partially, was mediated by down regulated JNK activation.

Objective To investigate the efficacy of prophylactic pancreatic stent placement and nonsteroidal antiinflammatory drugs( NSAIDs) for the prevention of post?endoscopic retrograde cholangiopan?creatography(ERCP) pancreatitis(PEP). Methods A total of 623 patients with high risk factors for PEP were treated with prophylactic pancreatic stent placement ( 145 patients, group A) or rectal NSAIDs( 478 pa?tients, group B) for PEP prevention by using the propensity score matching( PSM) analysis. Incidence of PEP, moderate and severe PEP were investigated. According to risk factors of PEP, indications of prophy?lactic pancreatic stent placement were analysed. Results Of 623 patients with high risk factors, 145 pairs were generated after PSM.Pancreatitis occurred in 32 patients,10 (6?9%) in group A and 22 (15?2%) in group B( P<0?05 ) . Moderate?to?severe pancreatitis developed in 5 ( 3?4%) patients in group A and 14 (9?7%) patients in group B(P<0?05).Risk factors of post?ERCP PEP were cannulation attempts duration longer than 10 minutes, precut sphincterotomy, more than one pancreatic guidewire passages and history of ampullectomy. Conclusion Although the NSAIDs represent an easy, inexpensive treatment, prophylactic pancreatic stent placement is still a better prevention strategy for PEP.Prophylactic pancreatic stents should be recommended to those with risk factors including cannulation attempts duration longer than 10 minutes, precut sphincterotomy, more than one pancreatic guidewire passages and ampullectomy.

Objective To establish a large animal ( sheep) model to serve the experiments of domestic pulsatile ventricular assist device.Methods Three small-tail Han-sheep were anesthetized and the vein access and artery access were achieved.The cardiopulmonary bypass was established through left thoracotomy.Ventricular fibrillation was induced. An hole was made in the apex of left ventricle and the apex cannulation was sutured to it.The aortic cannulation was su-tured to the descending aorta.The two cannulations were connected to the domestic pulsatile ventricular assist device ( DP-VAD) and the driver was turned on.The working of DPVAD and the conditions of the animals were observed.Results The DPVAD worked well and uni-directional blood flow was driven by positive and negative pressure.The left ventricle was unloaded and the blood pressure was raised up.Conclusion The establishment of sheep model of pulsatile ventrieular as-sist device may play important role for the research and development of DPVAD in our country.

Objective To analyze the clinical outcomes of patients treated with in vitro fertilization and embryo transfer (IVF-ET) and influence factors of pregnancy rate. Methods We retrospectively analyzed the clinical data of 12 491 cycles, including 6832 fresh IVF/intracytoplast single sperm injection (ICSI) cycles and 5659 frozen embryo transfer (FET) cycles from 2005 to 2007. Results The clinical pregnancy rate per cycle was 32. 99% (2254/6832)in fresh embryo transfer program, and the live birth rate was 25.75% (1394/5413); the early pregnant loss rate was 9. 36% (211/2254), and the prenatal defect rate was 1.45% (25/1722). Through analysis of these patients' basic data, we found that the patients' age, causes for infertility, egg retrieval and cycle number affected the pregnancy rate. Using logistic regression method, we found that patients′ age was the most important factor affecting pregnancy outcome. In FET cycles, the clinical pregnancy rate was 38.08% (2155/5659), significantly higher than fresh embryo transfer cycles. Conclusions IVF-ET treatment is a safe and effective method for infertility couples. However, the female age and poor ovarian response are the main factors affecting pregnancy rate. Thawed embryo transfer can increase the accumulated pregnancy rate effectively.

Objective To observe the efficacy and adverse reaction of Durogesic (thansdermal fenfanul) for analgesia in patients with malignant tumors, who occur moderate or severe pain from mucosal response during radiochemotherapy. Methods 50 patients were divided into two groups randomly. The treatment group received Durogesic and normal therapy, the contrast group received normal therapy. The analgesic effects, the quality of life and the side effects after medicine were observed. Results The pain remission rates of treatment group and control group were 100 % (25/25) and 52 % (13/25), respectively (χ2 =15.78, P ＜ 0.01)[(9.66±0.35), (10.01±0.34) min]and[(18.12±0.46), (14.68±0.19) min].The quality of life in treatment group was improved significantly (t = 8.11, P ＜0.01).The main adverse reactions of Durogesic included constipation, itch of skin, drowsiness, nausea, vomiting and so on. All of adverse reactions were tolerable. Conclusion Durogesic for analgesia have high curative effect and slight adverse effects in pain of oral cavity and laryngeal pharynx in patients with malignant tumors during radiochemotherapy which make patients complete radiochemotherapy successfully.

Objective To investigate the clinical value and the feasibility of strain-blood pressure index(SBPI) in assessing the elasticity of brachial artery and anterior tibial artery in patients with type 2 diabetes mellitus. Methods Forty-six type 2 diabetic patients and 50 healthy volunteers were involved. Maxmum of circumferential strain (CSmax) of brachial artery and anterior tibial artery were acquired through strain and strain rate imaging(Xstrain). Local systolic blood pressure(LSBP) and local diastolic blood pressure(LDBP) of brachial artery and anterior tibial artery were measured at the same time. SBPI,tibial-brachial index (TBI), and ankle-brachial index(ABI) were calculated, SBPI = CSmax/[(LSBP-LDBP) /LDBP]×100%,TBI = SBPI of anterior tibial artery/SBPI of brachial artery, ABI = LSBP of anterior tibial artery/LSBP of brachial artery. Parameters were compared between the case group and the control group. Results SBPI of anterior tibial artery and TBI had significant difference between the case group and the control group( P < 0.05), while SBPI of brachial and ABI had no significant difference( P >0. 05).Conclusions SBPI might be a new index for evaluating the elasticity of medium-sized arteries in patients with type 2 diabetes, and different changes caused by type 2 diabetes between brachial artery and anterior tibial artery could be reflected by TBI.
