Objective To study the expression of multidrug resistance associated protein 1 (MRP1) and MRP2 in the peripheral blood mononuclear cells of children with intractable epilepsy (IE).Methods During Nov.2010 to Oct.2013,50 children with I E were collected as the experimental group,simultaneously 50 children with epilepsy controlled by the anti-epileptic drugs (AEDs) and 50 healthy children without epilepsy were collected as the control group from the outpatient or inpatient of Xuzhou Children's Hospital.The expressions of MRP1 and MRP2 in the peripheral blood mononuclear cells of children were detected by reverse transcriptase polymerase chain reaction and Western blot.Results 1.The mean relative expression of MRP1 and MRP2 mRNA in the peripheral blood mononuclear cells of children with IE (0.795 ± 0.042,0.804 ± 0.023) were higher than those in epilepsy controlled by AEDs (0.682 ± 0.030,0.675 ± 0.021) and healthy children without epilepsy (0.665 ± 0.031,0.654 ± 0.029) (all P ＜0.001).2.The mean relative expression of MRP1 and MRP2 protein in the peripheral blood mononuclear cells of children with IE (2.027 ±0.034,1.902 ±0.021) were higher than those in epilepsy controlled by AEDs(1.131 ±0.042,1.086 ± 0.027) and healthy children without epilepsy (1.093 ± 0.023,1.045 ± 0.018) (all P ＜ 0.001).3.There was no difference in the expression of MRP1,MRP2 mRNA and proteins between the children with epilepsy controlled by AEDs and healthy children without epilepsy (all P ＞ 0.05).Conclusions MRP1 and MRP2 over-expression in the peripheral blood mononuclear cells of children with IE may be associated with drug-resistance mechanism for medically intractable epilepsy.

Objective To summarize the cases of surgical treatment of patients with patent ductus arteriosus (PDA),atrial septal defect(ASD),or ventricular septal defect(VSD) after failure of congenital cardiac catheterization(CCC).Methods From January 2000 to December 2013 in our hospital 26 patients were retrospectively studied,follow-up results recorded for each patient by telephone and outpatient follow-up review.Results There were no deaths.The average age of the patients was (18.8 ± 17.9) (3.0-67.0) years old.The median time of the intervals between interventions and surgeries were 14 days(2 hours to 5 years),the median length of hospital stay were 10 days(7-21 days),median cardiopulmonary bypass time was 67minutes (0-206 minutes),the median blocking time 40 minutes (0-90 minutes),the median time of mechanical ventilation 8.5 hours (2.0-88.0 hours),median ICU stay one day (1-6 days).The average follow-up were (93.0 ± 49.3) months (7.0-182.4 months).Surgical results were satisfactory.Conclusion Interventional treatment of congenital heart disease (CHD) is safe after all,but should strictly the indications controlled,the operations completed by skilled doctors.If there are complex complications,surgical intervention should be concerned,and the results are satisfactory.Patients after CCC should be followed up regularly.

Objective To observe the effects of 860 MHz microwave radiation on an established dual task model of trace and delay eyeblink conditioning in guinea pigs.Methods Twenty-four guinea pigs with an established dual task model of trace and delay eyeblink conditioning were assigned randomly into four groups : a microwave-exposed 1 h group, a microwave-exposed 20 min group, a sham-exposed group and a normal control group.The guinea pigs in the 1 h and 20 min groups were irradiated on the head daily for 3 days using 860 MHz electromagnetic radiation at a power density of 1 mW/cm2 for 1 h and for 20 min, respectively. After radiation the guinea pigs were trained with classical dual task eyeblink conditioning.Results Compared with the normal control group, the behavioral parameters (acquisition rate and peak amplitude of trace and delay eyeblink) of guinea pigs in the microwave-exposed 1 h group had decreased significantly with no obvious change in latency. The behavioral parameters of guinea pigs in the microwave-exposed 20 min group, the sham-exposed group and the normal control group showed no obvious change.Conclusions Microwave radiation at 860 MHz and 1.0 mW/cm2 for 1 h can cause changes in dual trace and delay eyeblink conditioning in guinea pigs and decrease learning and memory capacity.

This study was purposed to investigate the expression level of oncogene c-myc and c-myb in leukemic cells and leukemic bone marrow stromal cells (BMSC) and the correlation with each other. The expression levels of c-myc and c-myb in those cells were examined semi-quantitatively by reverse transcription polymerase chain reaction (RT-PCR). Flow cytometry analysis was used to detect the membrane surface antigens of leukemic cells and BMSC. The karyotype was analyzed by G-banding techniques. The results showed that (1) c-myc and c-myb gene were expressed in the normal control group, the leukemic cells and BMSC of patients group. The mean expression levels of c-myb mRNA and c-myc mRNA in abnormal chromosomal leukemic cells were 1.03 ± 0.48 and 1.15 ± 0.38 respectively, which were significantly higher than those in control group (P < 0.05). In the abnormal karyotype stromal cells, the mean expression level of c-myb mRNA and c-myc mRNA were 2.08 ± 0.82 and 1.46 ± 0.29 respectively (P < 0.05). (2) The expression level of c-myc and c-myb mRNA were closely associated with patients' platelet counts (P < 0.05). (3) The expression of c-myc mRNA linearly correlated with the expression of c-myb mRNA in different prognostic groups. (4) In acute leukemic cells and BMSC, c-myc expression positively correlated with c-myb expression. (5) The expression level of c-myc in leukemic cells correlated with the expression levels of c-myc and c-myb in BMSC, respectively. It is concluded that the reduction of c-myc or c-myb expression levels may be a therapeutic regimen for leukemia.

The continuous cultivation of Rehmannia glutinosa causes the accumulation of phenolic acids in soil. It is supposed to be the reason of the so called "continuously cropping obstacle". In this study, phenolic acids (hydroxybenzoic acid, vanillic acid, eugenol, vanillin and ferulic acid) were degraded by the extracta of all the tested spent mushroom substrate (SMS) and the maximal degradation rate was 75.3%, contributed by extraction of SMS of Pleurotus eryngii. Pot experiment indicated that hydroxybenzoic acid and vanillin in soil were also degraded effectively by SMS of P. eryngii. The employment of SMS enhanced ecophysiology index to near the normal levels, such as crown width, leaves number, leaf length, leaf width and height. At the same time, the fresh and dry weight and total catalpol concentration of tuberous root weight of R. glutinosa was increased to 2.70, 3.66, 2.25 times by employment of SMS, respectively. The increase of bacteria, fungi and actinomycetes numbers in rhizosphere soil were observed after the employment of SMS by microbial counts. The employment of SMS also enhanced the enzyme activity in soils, such as sucrase, cellulase, phosphalase, urease and catelase. These results indicated that the employment of SMS alleviated the continuously cropping obstacle of R. glutinosa in some extent.

BACKGROUND: There are many studies on Modic changes in patients with lumbar degenerative disease and low back pain. However, few studies facus on epidemiological distribution and related factors of Modic changes in cervical spine, and its epidemiology and influencing factors remain unclear.OBJECTIVE: To study the morbidity and distribution of Modic changes in patients with cervical and shoulder pain and its correlation with gender, age and cervical degeneration. METHODS: Totally 430 patients admitted in the Second Affiliated Hospital of Inner Mongolia Medical University and undergoing cervical MRI and CT examination due to neck and shoulder pain between December 2014 and December 2016 were retrospectively analyzed, involving 197 males and 233 females, aged 19-78 years (mean age: 50.3 years). The morbidity and segmental distribution of Modic changes and its correlation with age, sex, cervical intervertebral disc degeneration and facet joint degeneration were analyzed. RESULTS AND CONCLUSION: (1) Among 2 150 disc segments of 430 patients, 348 segments (16.2%) of 67 patients (15.6%) appeared with Modic changes:73(3.4%)segments were type I,243(11.3%)were type II,and 32(1.5%)were type III.(2)By application of chi-square test, Modic changes were most common at the C5/6segment; older than 40 years and Pfirrmann disc degeneration grade III were relevant factors, while gender and facet joint degeneration were not.

There is controversy regarding the roles of Ureaplasma urealyticum (U. urealyticum) colonization in the development of bronchopulmonary dysplasia (BPD). This study explored the association between U. urealyticum and bronchopulmonary dysplasia at 36 weeks post-menstrual age (BPD36). Studies published before December 31, 2013 were searched from Medline, Embase, Ovid, Web of Science, and Cochrane databases, with the terms "Ureaplasma urealyticum", "chronic lung disease", or "BPD36" used, and English language as a limit. The association between U. urealyticum colonization and BPD36 was analyzed with RevMan 4.2.10 software, using the odds ratio (OR) and relative risk (RR) for dichotomous variables. Out of the enrolled 81 studies, 11 investigated the BPD36 in total 1193 infants. Pooled studies showed no association between U. urealyticum colonization and subsequent development of BPD36, with the OR and RR being 1.03 (95% CI=0.78-1.37; P=0.84) and 1.01 (95% CI= 0.88-1.16, P=0.84), respectively. These findings indicated no association between U. urealyticum colonization and the development of BPD36.
