Objective To detect the expression of metallothionein-3 (MT-3)mRNA in human esophageal squamous cell carcinoma. Methods Five cell lines of human esophageal cancer,TE-1,TE-13,TTN,ECA-109 (cell lines of esophageal squamous cell carcinoma) and OE33 (cell lines of esophageal adenocarcinoma),were used in this study. RT-PCR was employed to detect the expression of MT-3 mRNA. Peripheral blood monouclear cells from normal subjects were served as controls. Results Sequencing of RT-PCR product certified the gene of MT-3 mRNA. It was revealed by gel electrophoresis that there was expression of MT-3 mRNA in each cell line. The relative expression of MT-3 mRNA was 0.230?0.023,0.516?0.020,0.140?0.009,0.176?0.015 and 0.085?0.011 in cell lines of TE-1,TE-13,TTN,ECA-109 and OE33,respectively,significantly lower than that in controls (0.762?0.026) (P

Objective To evaluate the efficacy and safety of colistimethate sodium (CMS) for the treatment of critical patients infected by pan-drug resistantAcinetobacter baumannii (PDR-AB) or pan-drug resistant Pseudomonas aeruginosa (PDR-PA).Methods 321 isolates of PDR-AB and 204 isolates of PDR-PA from critical patients admitted to 35 intensive care units (ICUs) of grade two or above were collected from the Anhui Antimicrobial Resistance Investigation Net (AHARIN) program from September 2012 to September 2015, while the minimal inhibitory concentrations (MIC) of colistin were determined by the E-test. A series of Monte Carlo simulations was performed for CMS regimens (1 MU q8h, 2 MU q8h, and 3 MU q8h, and MU meant a million of unit), and the probability of achieving a 24-hour area under the drug concentration time curve (AUC24)/MIC ratio > 60 and risk of nephrotoxicity for each dosing regimen was calculated. Each simulation was run over three CLCr ranges: < 60, ≥ 60-90, ≥ 90-120 mL/min. The probability of target attainment (PTA)for the AUC24/MIC ratio was calculated using the partial MIC value, while the cumulative fraction of response (CFR) was determined by integrating each PTA with the MIC distributions, the value greater than or equal to 90% or more than 80% was set as the optimal dosing regimen or suboptimal dosing regimen respectively. The probability of average 24-hour serum concentrations up to 4 mg/L for three dosage regimens was used to predict the risks of nephrotoxicity.Results All 321 isolates of PDR-AB and 204 isolates of PDR-PA were susceptible to colistin, the MIC50/90 against PDR-AB were 0.5mg/L and 1.0 mg/L, and those against PDR-PA were 0.5 mg/L and 1.5 mg/L, respectively. When recommended dose (1 MU q8h) was used for patients with CLCr of < 60 mL/min, high CFR value (89.78% for PDR-AB, 81.06% for PDR-PA) were obtained, but with a high risks of nephrotoxicity (> 32.51%). Moreover, low value of PTA (< 66.56%) was yielded for isolates with MIC of ≥ 1 mg/L. Recommended dose also yielded a low CFR value (56.97%-69.31% for PDR-AB, 44.76%-56.94% for PDR-PA) in patients with CLCr of ≥ 60-120 mL/min. When dose was increased to 2 MU q8h, CFR (77.45%-92.87%) and the risks of nephrotoxicity (< 0.15%) was optimal for patients with CLCr ≥ 60-120 mL/min, but low value of PTA (< 75.36%) was also yielded for isolates with MIC of ≥ 1 mg/L. The most aggressive dose of 3 MU q8h provided high CFR (> 89.24%) even in patients with CLCr ≥ 90-120 mL/min, and PTA was < 76.20% only for isolates with MIC of ≥ 1.5 mg/L, but this dosing scheme was associated with unacceptable risks of nephrotoxicity (> 33.68%).Conclusion Measurement of MIC, individualized CMS therapy and therapeutic drug-level monitoring should be considered to achieve the optimal drug exposure and ensure the safety of CMS.

Objective To investigate the effects of total anthraquinone in rheum on aquaporin 2 and aquaporin 4 expression in rat kidney and explore its diuresis mechanism.Methods Thirty-two SD rats were randomly divided into control group,low dose group,medium dose group and high dose group.Total anthraquinone in rheum was administered to rats at different doses.Urinary volume of 24 h,Na+ concentration and osmolality were detected.Rats were sacrificed 5 days later.Blood samples were taken from the abdominal aorta to detect blood biochemical indicators. Kidneys of rats were removed to detect AQP2, AQP4 expression through immunohistochemistry,Western blot,and RT-PCR. Results Compared with control group,there were significantly increased 24 h urine output of rats in medium and high dose group[(16.21±1.96),(18.16±1.8) ml vs(13.85±1.25)ml,P＜0.05].24 h urine output in low-dose group did not change significantly.AQP2 protein and mRNA expression were significantly decreased in rats'kidneys of medium and high dose group (P＜0.01),The AQP4 protein and mRNA expression was significantly down-regulated in high dose group (P＜0.01).In medium does group,the AQP4 protein expression was down-regulated (P＜0.01),without significant decrease in the mRNA expression.Protein and mRNA expression of AQP2 and AQP4 did not significantly change in low dose group.Conclusion Total anthraquinone in rheum can reduce the expression level of AQP2 and AQP4 in rat kidney,which is probably one mechanism of diuresis caused by rheum.

Objective To investigate the factors associated with hyporesponsiveness to erythropoietin (EPO) in patients on maintenance peritoneal dialysis (PD) . Methods Data of 114 PD patients in our PD center were collected . Patients were divided into three groups according to weekly EPO dose: hyperresponsive, hyporesponsive and normal responsive . Various factors were compared among three groups by linear correlation and ordinal regression analysis to predict EPO resistance . Results As compared to hyperresponsive and normal responsive groups,significantly lower serum hemoglobin [(78 .11±13 .42) vs (106 .28±23 .83), (96 .31±12 .33) g/L],albumin [(33 .98±4 .78) vs (39 .72±4 .26), (35 .76±4 .88) g/L], and significantly higher serum CRP [(26 .08±21 .66) vs (5 .46±1 .75), (11 .82±5 .63) mg/L], ferritin [(371 .08±89 .38) vs (289 .39±76 .84),(323 .07±62 .46) μg/L] were found in hyporesponsive group(all P ＜ 0 .01) . Erythropoietin resistance index (ERI) was correlated with CRP and albumin . Regression analysis showed that serum albumin,CRP and ferritin were strong predictors of EPO hyporespnsiveness . Conclusions Serum albumin,CRP and ferritin are closely related to hyporesponsiveness . Malnutrition and inflammatory state contribute to EPO hyporesponsiveness .

Objective To assess the efficacy of intedeukin (IL)-1Ra,a recombinant human IL-1receptor antagonist,plus methotrexate ( MTX ) in patients with active rheumatoid arthritis ( RA ) refractory to MTX therapy.Methods A total of 54 patients with active RA,who had been taking MTX at a stable dosage,were randomized to receive daily subcutaneous injections of IL-1Ra (80 mg) or placebo.The proportion of patients who had a response as assessed by ACR20,ACR50 and ACR70 was analyzed using Chi-square test measures.Baseline variables and DAS28 were analyzed using Student's t-test (parametric) or Wilcoxon's rank sum test (nonparametric) as appropriate.Results After 24 weeks,more patients achieved clinical benefits treated with IL-1Ra plus MTX compared with MTX alone (64％ vs 17％,P=-0.004) as determined by the ACR20 improvement.In the IL-1Ra group,an ACR50 response was observed in 38％ and an ACR70 response in 17％.None of the patients treated with MTX alone achieved ACR50 or ACR 70 improvement.However,9 of 42 (21％) patients in the IL-1Ra group,who showed therapeutic response initially,had secondary drug failure to IL-1Ra therapy thereafter.A significant increase in mean DAS28 from baseline was found in the nonresponders to IL-1Ra,compared with placebo.Conclusion IL-IRa is effective for the treatment of patients with active RA by blocking IL-1.However,the efficacy of IL-1Ra is lost soon in about one-fifth of patients in soite of initial good resoonse.

Objective Therapeutic hypothermia has become a standard neuroprotective treatment in term newborn infants following perinatal asphyxia,but active cooling with whole body surface or head cooling is both complex and expensive.The clinical feasibility of passive cooling in treatment of full term infants with severe asphyxia was investigated.Methods Thirty-two severe asphyxiated term newborns treated with hypothermia were analyzed,who were randomly divided into 2 groups:passive cooling group(n =17) and active cooling group(n =15).Active cooling group adopted MTRE ALLONTM-thermo regulatory systems,passive cooling group using natural cooling method.Hypothermia treatment time was 72 hours.At the end of treatment,the clinical manifestations,biochemical parameters and clinical efficacy of infants between the 2 groups were compared.Results During treatment all infants had no cardiac arrhythmia,hypoglycemia,sustained metabolic acidosis,blood-borne infections,local cold injury or bleeding.Infants in passive cooling group had a relatively wide range of rectal temperature fluctuations[average (33.47-0.71) ℃] and infants in active cooling group had a relatively narrow range of rectal temperature fluctuations[average (33.66 ± 0.29) ℃],but there was no statistically significant difference in their mean rectal temperature(t =1.941,P =0.055).One patient died in active cooling group,but there were no significant differences in suckling age,length of hospital stay,neonatal behavioral neurological assessment score,abnormal cranial ultrasound and MRI between the survivors of the two groups(all P ＞0.05).Conclusions In NICU,environmental temperature is relatively stable,passive cooling for asphyxiated newborns appears to be feasible for maintenance of hypothermia with a lower risk of adverse reactions.

Objective To investigate thc cvent-based prospective memory (EBPM)and time-based prospective memory(TBPM)in the inpatients with abstinent alcohol dependence and the relationships between prospective memory and symptoms.Methods 32 male patients with alcohol dependence and 30 normal controls matched by age,education,HAMD and HAMA were assessed with a neuropsychological battery of tests including EBPM and TBPM tasks.Results A statistically significant in EBPM was observed between patients with alcohol dependence and normal controls (3.91 ± 0.69 vs.4.47 ± 0.63,t =-3.348,P ＜ 0.0 1) and the same result in TBPM (3.28 ±0.77 vs.4.20 ±0.66,t=-5.032,P＜0.01).The positively correlation was showed between the duration of abstinence and EBPM (r =0.444,P ＜ 0.05),as well as TBPM (r =O.423,P ＜ 0.05) in the patients.Conclusion The results suggest abstinent alcohol dependence patients impairs both EBPM and TBPM.PM shows correlated with duration of abstinence moderately in the patients.

Objective To evaluate whether the serum uric acid (SUA) levels are related to development of prediabetes. Methods This was a 6-year cohort study, subjects were recruited from Tianjin Medical University General Hospital Health Management Center. A prospective assessment (n=30 910) was performed. Subjects without a history of prediabetes were followed up for 6 years (with a median follow-up of 2.7 person-years). All relevant variables including SUA concentrations, and fasting plasma glucose were assessed at baseline and yearly during the follow-up. Prediabetes was defined in accordance with the American Diabetes Association criteria of 2014. Multivariate-adjusted Cox proportional hazards regression models were fitted to assess relationships between the quintiles of baseline SUA and the incidence of prediabetes. Results The incidence of prediabetes was 55 per 1 000 person-years. In comparison with subjects in the lowest quintile, the odds ratios and hazard ratio (95%confidence interval) of higher quintile of SUA were 1.04 (0.93, 1.15), 1.07 (0.95, 1.19), 1.13 (1.01, 1.28) and 1.15 (1.02, 1.30) (P for trend=0.01), respectively, after adjusting for potential confounders. Conclusion SUA levels predicted an increased risk of prediabetes in adults.
