11.1 mmol/L were treated by 2 weeks CSII.An intravenous glucose tolerance test(IVGTT) was performed before and after CSII.The levels of fasting plasma glucose(FPG),2 hours postprandial glucose(2hPG),glycosylated hemoglobin A1c(HbA1c),first-phase secretion of insulin,the mean area under the curve(AUC) of insulin,insulin sensitivity index(ISI),insulin resistance index(Homa IR) and insulin secretion index(Homa ?) were compared.Results The excellent control of FPG and 2hPG in 20 out of 21 patients were achieved stably in 2.8?1.6 days and 7.8?1.9 days by CSII.After the treatment,FPG,2h PG and HbA1c were significantly decreased(P

Objective To observe the effects and mechanism of lung inflation with carbon monoxide (CO) during the cold ischemia phase on lung ischemia-reperfusion injury (IRI) after rat lung transplantation.Method Twenty-four pairs of SD rats were selected to establish the model of lung transplantation,and random number method was used to divide 24 donors into 3 groups with 8 rats in each group.(1) CO inflation group (CO group):During the cold ischemia phase,500 ppm CO +volume fraction 40％ O2 + N2 was used for lung inflation,and the volume was 5 mL/kg;(2) O2 inflation group (O2 group):During the cold ischemia phase,volume fraction 40％ O2 + volume fraction 60％ N2 was used for lung inflation;(3) Control group:The lung was deflated during the cold ischemia phase.The gas was replaced every 30 min in the CO and O2 groups,and the lung transplantations were performed after 180 min of cold ischemia.The arterial blood gas analysis was performed at baseline,3 min after reperfusion,and 60,120,and 180 min after reperfusion.The recipient serum levels of relative inflammatory factors,lung tissue cell apoptosis and nuclear factor kappa B (NF-κB) protein expression were detected after 180 min of reperfusion.Result As compared with the control group (238 ± 61 mm Hg),the oxygenation index in the O2 group (293 ± 78 mm Hg) and CO group (361 ± 48 mm Hg) was increased (P＜0.05),and as compared with the O2 group,that in the CO group was increased (P＜0.05).Furthermore,as compared with the control group,the interleukin (IL)-8,tumor necrosis factor (TNF)-α,and cell apoptosis in the O2 group and CO group were decreased significantly,and as compared with the O2 group,those in the CO group and NF-κB protein expression were significantly decreased (P＜0.05).Conclusion Lung inflation with CO during the cold ischemia phase ameliorated the rat lung IRI via reducing the inflammatory response and cell apoptosis mediated by the NF-κB pathway.

Background: Neurolytic celiac plexus block (NCPB) is a typical treatment for severe epigastric cancer pain, but the therapeutic effect is often affected by the variation of local anatomical structures induced by the tumor. Greater and lesser splanchnic nerve neurolysis (SNN) had similar effects to the NCPB, and was recently performed with a paravertebral approach under the image guidance, or with the transdiscal approach under the guidance of computed tomography. This study observed the feasibility and safety of SNN via a transdiscal approach under fluoroscopic guidance. Methods: The follow-up records of 34 patients with epigastric cancer pain who underwent the splanchnic nerve block via the T11-12 transdiscal approach under fluoroscopic guidance were investigated retrospectively. The numerical rating scale (NRS), the patient satisfaction scale (PSS) and quality of life (QOL) of the patient, the dose of morphine consumed, and the occurrence and severity of adverse events were recorded preoperatively and 1 day, 1 week, 1 month, and 2 months after surgery. Results: Compared with the preoperative scores, the NRS scores and daily morphine consumption decreased and the QOL and PSS scores increased at each postoperative time point (P < 0.001). No patients experienced serious complications. Conclusions SNN via the transdiscal approach under flouroscopic guidance was an effective, safe, and easy operation for epigastric cancer pain, with fewer complications.

A group of benign Theileria species, which are often referred to as T. orientalis/T. buffeli/T. sergenti group, has low pathogenicity in cattle. Herein, we report on Theileria spp. in cattle on a farm from China. Based on phylogenetic analysis of the major piroplasm surface protein gene sequences, we detected 6 genotypes that were categorized as Types 1, 2, 3, 4, and 5 as well as an additional Type 9 genotype. The new epidemiological features of the T. orientalis/T. buffeli/T. sergenti parasites in China indicate a greater diversity in the genetics of these species than had been previously thought.

Objective To evaluate the effect of hydrogen preconditioning during cold ischemia phase on the activity of nuclear factor erythroid 2-related factor 2 ( Nrf2) in rat pulmonary microvascular en-dothelial cells ( PMVECs) subjected to hypoxia-reoxygenation ( H/R) . Methods PMVECs were isolated from clean-grade male Sprague-Dawley rats, aged 2-3 weeks, using the tissue block adherence method and divided into 4 groups ( n=25 each) using a random number table method: control group ( group C) , H/R group, oxygen group ( O group) and hydrogen group ( H group) . Cells were incubated for 4 h with 4℃ low potassium dextransolution ( LPD) pre-equilibrated with 95％ oxygen and 5％ carbondioxide to simulate the cold ischemia phase. LPD pre-balanced with 95％ oxygen and 5％ carbon dioxide was replaced with LPD, and then cells were incubated for 1 h at room temperature to simulate the lung transplantation period. LPD was rapidly replaced with 37℃ M199 complete culture solution, and cells were incubated in the mixture of 40％ oxygen-5％ carbondioxide-55％ nitrogen to simulate the reperfusion period. In O and H groups, the cells were exposed to 40％ oxygen-60％ nitrogen and 3％ hydrogen-40％ oxygen-57％ nitrogen during the cold ischemia period, respectively, and the gas mixture was replaced every 20 min. The cell culture fluid was collected 4 h later for determination of interleukin ( IL )-6, IL-10 and tumor necrosis factor-alpha ( TNF-α) concentrations ( by enzyme-linked immunosorbent assay) and malondialdehyde ( MDA) concen-trations ( by thiobarbituric acid method) . The cytoplasm and nucleoproteins were extracted for measurement of Nrf2 expression ( by Western blot) and cell apoptosis ( by flow cytometry and TUNEL assay) . The cell apoptosis rate was calculated. Results Compared with C group, the IL-6, TNF-α and MDA levels were significantly increased, the IL-10 level was decreased, the apoptosis rate was increased, and the expres-sion of Nrf2 in nucleus was up-regulated in H/R group ( P＞0. 05) . Compared with H/R group, the IL-6, TNF-α and MDA levels were significantly decreased, the IL-10 level was increased, the apoptosis rate was decreased, and the Nrf2 expression in cytoplasm was down-regulated in O and H groups (P＜0. 05), the Nrf2 expression was significantly up-regulated in H group ( P＜0. 05) , and no significant change was found in the expression of Nrf2 in nucleus in O group ( P＞0. 05) . Compared with O group, the IL-6, TNF-αand MDA levels were significantly decreased, the IL-10 level was increased, the apoptosis rate was decreased, the expression of Nrf2 in nucleus was up-regulated, and the expression of Nrf2 protein in cytoplasm was down-regulated in H group ( P＜0. 05 ) . Conclusion The mechanism by which hydrogen preconditioning during cold ischemia phase reduces H/R injury to rat PMVECs is related to activating Nrf2 and thus inhibi-ting oxidative stress.

OBJECTIVETo explore the incidence of chromosome 1 abnormality in myelodysplastic syndrome（MDS）to couple its association with clinical presentation and prognosis.

METHODSR- band karyotype analyses were performed in 672 cases of MDS between 2010 and 2013. Clinical data of those with abnormal chromosome l were collected and then analyzed factors affecting the prognosis.

RESULTSOf 672 cases of patients with MDS, chromosome 1 aberration［der（1）, dup（1）, －1 were most frequent］ were found in 41（6.1%）cases. 1q trisomy was found in 18/41（43.9%）cases, and the most common patterns were duplication of the long arm as well as unbalanced translocation with other chromosomes. Of 41 patients with chromosomal 1 abnormality, 32 cases were accompanied with other chromosomal aberration, usually involving 3 or more abnormal chromosomal karyotypes, e.g., chromosome 8, 7 abnormalities. According to IPSS-R scoring system, 19 patients were diagnosed with very high risk, 10 patients high risk, 10 patients intermediate risk and 2 patients low risk MDS. 9 patients transformed into acute leukemia with median transforming time of 7.18（0.56-54.28）months. Median survival of 36 cases after 2010 was 17.48（95% CI 14.38-20.58）months. There were significant differences on median survival between RAEB and non-RAEB groups（χ²=10.398, P=0.001）, and between with more than 3 chromosome abnormalities and with less than 3 groups（χ²=3.939, P=0.047）. RAEB was identified as an independent risk factor for the prognosis of MDS with chromosome 1 abnormality.

CONCLUSIONChromosome 1 aberration was not rare in MDS. 1q trisomy was the most common abnormal karyotype in China, which often accompanied with other chromosomal abnormalities. The prognosis of MDS patients with chromosome 1 abnormality was poor, especially worse in those diagnosed with RAEB-1, RAEB-2 and with more than 3 chromosome abnormality. For patients whose percentage of bone marrow blasts less than 5%, the prognosis of patients with 1q trisomy was better than those without 1q trisomy. RAEB was identified as an independent risk factor for the prognosis of MDS with chromosome 1 abnormality.

Obeticholic acid (OCA), the first FXR-targeting drug, has been claimed effective in the therapy of liver fibrosis. However, recent clinical trials indicated that OCA might not be effective against liver fibrosis, possibly due to the lower dosage to reduce the incidence of the side-effect of pruritus. Here we propose a combinatory therapeutic strategy of OCA and apoptosis inhibitor for combating against liver fibrosis. CCl-injured mice, d-galactosamine/LPS (GalN/LPS)-treated mice and cycloheximide/TNF (CHX/TNF)-treated HepG2 cells were employed to assess the effects of OCA, or together with IDN-6556, an apoptosis inhibitor. OCA treatment significantly inhibited hepatic stellate cell (HSC) activation/proliferation and prevented fibrosis. Elevated bile acid (BA) levels and hepatocyte apoptosis triggered the activation and proliferation of HSCs. OCA treatment reduced BA levels but could not inhibit hepatocellular apoptosis. An enhanced anti-fibrotic effect was observed when OCA was co-administrated with IDN-6556. Our study demonstrated that OCA inhibits HSCs activation/proliferation partially by regulating BA homeostasis and thereby inhibiting activation of HSCs. The findings in this study suggest that combined use of apoptosis inhibitor and OCA at lower dosage represents a novel therapeutic strategy for liver fibrosis.
