Lots of studies implicate that pathological high-frequency oscillation (HFO) was associated with epilepsy. In recent years, new recording technologies have advanced such that, at high temporal and spatial resolutions, high-frequency oscillation can be recorded in partial epilepsy by intracranial electrodes. More and more researchers focus on the study of high frequency oscillation. The techniques, which were used to record, automatic mine, analysis and quantify high-frequency oscillation, are develop quickly. As a new biomarker of epilepsy, high-frequency oscillation can reflect the epileptic form activity. The HFO has a great value in localization of human epileptic brain and epilepsy surgery.

Objective To establish the biological reference intervals of serum immunoglobulin ( Ig) for children ( neonates to young adults) in our laboratory.Methods This was a retrospective study.Serum IgG, IgA and IgM of the neonatal ( 1-28 days ) to 18 years old who visited the First Hospital of Jilin University during January 2011 to July 2014 were measured.The inclusion criteria were normal C-reactive protein content, normal liver and kidney function and without history of chronic diseases, allergic reactions, connective tissue diseases, rheumatic diseases and human immunodeficiency diseases.Children whose Ig tests were below upper limit of adult reference range were divided into 19 age groups.By eliminating outliers within each group, 9 466 cases of reference individuals conformed to the establishment of reference intervals were selected.Rank sum test was applied in comparing Ig levels of each two adjacent age groups, if there was not statistical significance ( P>0.05 ) , the two age groups were merged; otherwise not merged.The upper and lower limit of Ig reference range for each age group were calculated using nonparametric method, and biological reference intervals of children′s serum Ig were established.Results The neonatal serum IgG decreased grually after birth and reached the lowest point at 29 days-3 months, then the concentration increased gradually along with age growth and reached adult level by 11 years old.Neonatal serum IgA and IgM levels were at the lowest point and the concentration increased along with age growth then reached adult levels by 11 and 2 years old respectively.The children′s serum Ig reference intervals were as below:IgG:3.59-7.90, 2.26-5.40, 2.72-6.62, 2.87-7.74, 3.38-8.07, 3.80-9.08, 4.86-11.40, 4.97-11.70, 5.51-12.40, 6.17-13.10, 6.41-13.60, 6.53-14.20 and 6.84-14.30 g/L for neonatal, 29 days-3 months, 4-6 months, 7 months, 8-9 months, 10 months-1 year old, 2, 3, 4, 5-6, 7, 8 and 9-10 years old, respectively;IgA:0.23-0.45, 0.24-1.02, 0.23-0.79, 0.23-0.92, 0.24-1.03, 0.24-1.56, 0.26-1.93, 0.31-2.16, 0.44-2.56, 0.56-2.85, 0.52-3.35 and 0.63-3.23 g/L for neonatal-3 months, 4 months, 5-7 months, 8-9 months, 10 months-1 years old, 2, 3, 4, 5-6, 7, 8, and 9-10 years old, respectively;IgM:0.16-0.70, 0.21-1.20, 0.30-1.62, 0.38-2.16 and 0.44-2.17 g/L for neonatal, 29 days-3 months, 4-7 months, 8-9 months and 10 months-1 years old, respectively.Conclusions There were great differences of the serum Ig concentrations between children and adults, thus children′s immunologic function should not be assessed based on adult Ig reference intervals.According to the research, reference intervals of Ig were obtained for children at different age groups in the laboratory and reference in evaluating children′s immunologic function was provided for clinicians.

Objective To observe the clinical efficacy of Tanreqing Injection combined with levofloxacin injection in treatment of acute episode of chronic bronchitis and its effect on bacterial clearance rate. Methods Totally 66 patients were randomly divided into treatment group and control group (33 cases for each). Both groups were given expectorant and antispasmodic treatment. The treatment group was given Tanreqing Injection combined with levofloxacin injection, while the control group was given levofloxacin injection only. The treatment course was 12 days. The clinical symptoms, signs, and sputum culture before and after treatment were observed. The clinical efficacy and the bacterial clearance rate of the two groups were compared. Results The markedly effective cases and the effective cases in the treatment group were 15 and 29 respectively, and those in the control group were 7 and 21 respectively, with statistical significance (P<0.05). The bacterial clearance rate was 89.5% (17/19) in the treatment group, while 55.6%(10/18) in the control group, with significant difference (P<0.05). Conclusion Acute episode of chronic bronchitis treated by Tanreqing Injection combined with levofloxacin injectcion is more effective than levofloxacin injection only.

OBJECTIVE To investigate the effect of Hath1 on epithelial ridge (GER) cells from postnatal rat cochlear. METHODS An experimental method was developed which allowed the isolation and culture of GER cells from P1 rat cochleae using a combinatorial approach of enzymatic digestion and mechanical separation. The dissociated GER cells were cultured in DMEM+10% FBS. The GER explants infected with ad-Hath1 for 3 hours were cultured for 10 days and observed under scanning electron microscope. RESULTS The GER cell cultures tended to attach to the substratum and grow in patches which assume a polygonal morphology similar to that of epithelial cells in medium containing 10% serum. Stereociliary bundle-like structures were observed in the boundary of GER cell patches forced to express Hath1. CONCLUSION That GER cells which are likely hair cell progenitors could be cultured in vitro and generate stereociliary bundle-like structure when forced to express Hath1 suggests that the misexpression of Hath1 probably can induce the predifferentiation of pure hair cell progenitors into hair cells in vitro.

This paper was aimed to study the genetic diversity and genetic relationship of germplasm resource of Lonicerae Japonicae Flos in order to provide references for its breeding. A total of 36 samples from 18 farm varieties and wild species, as well as related species of Lonicera japonica Thunb. from the main production areas were studied by ISSR-PCR markers. The Jaccard coefficient was worked out by NTSYS-pc software. And a cluster dendrogram of different samples was established based on unweighted pair-group method with arithmetic mean (UPGMA). The re-sults showed that 12 ISSR primers generated 129 loci of which 114 loci were polymorphic. The average percentage of polymorphic bands (PPB) is 88.37%. In the cluster dendrogram, different samples of Lonicera japonica are in the same group, which showed that it is a natural species; the wild sample is separated from the cultivated samples; the traditional type-Maohua is relative stable, but the type of Jizhuahua includes complicated varieties, and it has obvi-ous genetic variation; the new variety Jiufeng 1 has already distinct into one stable type. It was concluded that the ISSR method was suitable for germplasm identification, genetic diversity analysis of Lonicerae Japonicae Flos, thus providing a theoretical foundation for its cultivation and breeding.
