Objective:To study the expressions of serum levels of intedeukin-12 (IL-12),interferon-γ (IFN-γ),erythropoietin (EPO) and ferritin in patients with acute leukemia and its clinical significance.Methods:76 patients with acute leukemia who were treated in our hospital from July 2015 to July 2016 were selected as the observation group,including 31 cases of newly diagnosed group,25 cases of remission group and 20 cases of relapse group.And another 76 cases who had taken the physical examination in our hospital were selected as the control group.Then the levels of serum IL-12,IFN-γ,EPO and ferritin in patients were observed and compared between the two groups.Results:The levels of IL-12 and IFN-γ in the observation group were significantly lower than those of the control group,and the levels of EPO and ferritin were significantly higher than those of the control group (P ＜0.05).The levels of serum IL-12 and IFN-γ in the untreated group and the relapse group were significantly lower than those of the remission group [(84.21± 5.43)pg/mL,(98.7± 7.98)pg/mL VS(112.43± 10.21) pg/mL,(38.54± 3.56)pg/mL,(49.87± 4.02)pg/mL VS(108.32± 8.43)pg/mL](P ＜0.05),and the levels of EPO and ferritin were significantly higher than those of the remission group [(402.32± 42.31) mIU/mL (321.58± 30.21)mIU/mL VS (98.21 ± 9.45) mIU/mLM (653.21 ± 54.24) ng/mLM (512.87 ± 43.45)ng/mL VS (342.15 ± 25.12)ng/mL] (P＜0.05).Conclusion:The serum levels of IL-12 and IFN-γ in patients with acute leukemia were lower,and the expression of EPO and ferritin was higher,and the disease and prognosis could be evaluated by monitoring the changes of these indexes.

Objective To investigate in vitro combined effect of ceftriaxone and azithromycin against clinical isolates of Neisseria gonorrhoeae(NG). Methods A total of 25 NG clinical isolates were collected from the STD clinic of Dalian Dermatosis Hospital in 2012. Epsilometer test(Etest)method was used to determine the minimum inhibitory concentrations(MICs)of ceftriaxone and azithromycin against NG isolates. Fractional inhibitory concentration index (FICI) was calculated to evaluate the in vitro combined effect of ceftriaxone and azithromycin against NG isolates. Results The mean MICs of ceftriaxone and azithromycin were 0.032 mg/L (range, 0.008- 0.064 mg/L) and 0.834 mg/L (range, 0.064-4.000 mg/L), respectively. The FICI ranged from 0.724 to 2.696, and ceftriaxone and azithromycin showed an additive effect against the above NG isolates. Conclusion Ceftriaxone and azithromycin show an additive effect against NG in vitro, but further studies with large sample size are needed to confirm their effects.

Objective To explore the clinical feature,suitable treatment and prognosis of soft tissue leiomyosarcoma of the trunk and extremities.Methods Clinical data of 18 cases of pathologically confirmed soft tissue leiomyosarcoma of the trunk and extremities from January 1999 to December 2012 were analyzed retrospectively.Primary tumors in 7 cases were marginally excised before admitted to our hospital,2 had open biopsy before admission to our hospital,and 8 cases had local relapse at admission; Only one patient took our institute as the first visit.Seventeen cases were performed extended excision of tumors and 1 case underwent marginal resection.All the patients were followed up and the follow-up period was from 16 to 158 months.Results During follow-up period,9 patients developed lung metastasis,and local recurrence occurred in 5 patients.Ten patients died and 8 survived.Of the ten dead cases,seven died of tumor progression and 3 died from non-tumor factors.In the 8 patients survived,2 survived with tumor.The 5-year overall survival rate was 59.2％.Conclusion Soft tissue leiomyosarcoma of the trunk and extremities are rare malignant tumors,mostly occurred in elder patients and presenting soft tissue mass.Local recurrence and distant metastasis are common and associated with a poor prognosis.Surgical excision combined with adjuvant radiation is the common treatment strategy.

OBJECTIVE To investigate the effect of sodium ferulate (SF) on lipopolysaccharide (LPS)-induced preterm delivery and intra-uterine fetal death (IUFD). METHODS Pregnant Kunming mice were subcutaneously pretreated with SF (25 or 50 mg · kg-1) from gestational day (GD) 10 to GD 15 and with the single injection of LPS (150μg·kg-1, ip) on GD15.5. The incidence of preterm delivery and IUFD was observed. HE staining was used for uterine and placental histological evaluation. The levels of thiobarbituric acid reactive substances (TBARS) and reduced glutathione (GSH) as well as the activities of glutathione S-transferase (GST) and glutathione peroxidase (GSH-Px) were detected in the maternal liver, placenta, and fetal liver using commercial kits. Interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) levels in amniotic fluid were evaluated by enzyme linked immunosorbent assay. RESULTS For LPS group, the incidence of preterm was 47.8%, delivery time was (17.5 ± 1.3) d, and the pups′survival rate was only 42.6%. Compared with LPS-treated group, SF 50 mg · kg-1 group showed a lower incidence of preterm (14.3%, P<0.01), longer gestational days (18.4 ± 0.5, P<0.05), and a higher pups′survival rate (75.6%, P<0.01). SF 50 mg · kg-1 restored the LPS-induced GSH both in the maternal and fatal liver (a tendency without statistical significance), GST activity〔(163±82) kU·g-1 protein vs (95±90) kU·g-1 protein, P<0.01)〕in the placenta, TBARS content〔(2.5±0.4)μmol·g-1 protein vs (3.1±0.6)μmol·g-1 protein, P<0.01〕in the fetal liver, and TNF-αlevel〔(11±8) ng·L-1 vs (20±8) ng·L-1, P<0.01〕in the amniotic fluid. SF also attenuated LPS-induced placental congestion and neutrophil infiltra?tion in the uterus. CONCLUSION SF may protect against LPS-induced preterm delivery and IUFD, and anti-oxidation as well as anti-inflammation may contribute to these effects.

Background Hyperuricemia is frequently present in patients with heart failure. Many pathological conditions, such as tissue ischemia, renal function impairment, cardiac function impairment, metabolic syndrome, and inflammatory status, may impact uric acid (UA) metabolism. This study was to assess their potential relations to UA metabolism in heart failure. Methods We retrospectively assessed clinical characteristics, echocardiological, renal, metabolic and inflammatory variables selected on the basis of previous evidence of their involvement in cardiovascular diseases and UA metabolism in a large cohort of randomly selected adults with congestive heart failure (n = 553). By clustering of indices, those variables were explored using factor analysis. Results In factor analysis, serum uric acid (SUA) formed part of a principal cluster of renal functional variables which included serum creatinine (SCr) and blood urea nitrogen (BUN). Univariate correlation coefficients between variables of patients with congestive heart failure showed that the strongest correlations for SUA were with BUN (r = 0.48, P < 0.001) and SCr (r = 0.47, P < 0.001). Conclusions There was an inverse relationship between SUA levels and measures of renal function in patients with congestive heart failure. The strong correlation between SUA and SCr and BUN levels suggests that elevated SUA concentrations reflect an impairment of renal function in heart failure.

BackgroundThe relationship between lipids and coronary artery disease has been well established. However, this is not the case between lipids and heart failure. Ironically, high lipid levels are associated with better outcomes in heart failure, but the mechan-isms underlying the phenomenon are not fully understood. This study was performed to test the hypothesis that reduced intestinal lipid absorption due to venous congestion may lead to low lipid levels.MethodsWe collected data of clinical characteristics, echocardio-graph, and lipid profile in 442 unselected patients with congestive heart failure. Correlations between lipid levels[including total cho-lesterol(TCL), high-density lipoprotein cholesterol(HDL-C), low-density lipoprotein cholesterol(LDL-C), and triglycerides(TG)]and right ventricle end diastolic diameter (RVEDD), left ventricle end diastolic diameter (LVEDD), right atrium diameter (RA), left atrium diameter (LA), or left ventricle ejection fraction (LVEF) were analyzed using Pearson correlation and partial correlation. RVEDD, LVEDD, RA, and LA were indexed to the body surface area.ResultsThere was a significantly inverse correlation between TCL le-vels and RVEDD (r=-0.34,P<0.001) and RA (r=-0.36,P<0.001). Other lipids such as LDL-C, HDL-C, and TG had asimilar inverse correlation with RVEDD and RA. All these correlations remained unchanged after adjusting for age, gender, smoking status, physical activity levels, comorbidities, and medication use.ConclusionsLipid levels were inversely correlated to RVEDD in patients with congestive heart failure; however, because this was an observational study, further investigation is needed to verify our results as wellas identify a causal relationship, if any.
