OBJECTIVE:
To observe the correlation between the threshold of tone burst auditory brain stem response (Tb-ABR) and ASSR (auditory steady-state response) and the threshold of BA (behavioral audiometry). To investigate the accuracy and clinical value of Tb-ABR and ASSR in pediatric hearing assessment.
METHOD:
From January, 2014 to December, 2014, 76 children (123 ears) recieved hearing examination in the First Affiliated Hospital of Zhengzhou University. They were classified into three groups according to the hearing level: 23 children (46 ears) with normal hearing ability in group A, 27 children (32 ears) with slightly-moderate sensorineural deafness in group B and 26 children (45 ears) with severe-profound sensorineural deafness in group C. Tb-ABR, ASSR, BA in 4 frequencies (0.5, 1.0, 2.0, 4.0 kHz) were tested and the results were statistically analyzed.
RESULT:
(1) At the 4 frequencies (0.5-4.0 kHz), we obtained 132 thresholds of Tb-ABR, 144 of ASSR, 152of BA. And 166 thresholds were obtained in Tb-ABR+ASSR+BA in total . (2) The thresholds of Tb-ABR, ASSR and those of BA in all 3 groups had linear relations at 0.5-4.0 kHz. The correlation coefficients of group A were 0.76, 0.82, 0.87 and 0.91; 0.52, 0.57, 0.67 and 0.64. Those of Group B were 0.89, 0.95, 0.98 and 0.95; 0.74, 0.82, 0.87 and 0.90. Those of Group C were 0.91, 0.90, 0.92 and 0.89; 0.93, 0.95, 0.95 and 0.91.
CONCLUSION
(1) Both ASSR and Tb-ABR can allow reasonably accurate predictions for the pediatric hearing assessment. The correlation between Tb-ABR threshold and BA threshold is higher in normal hearing children and slightly-moderate sensorineural deafness children. The correlation between ASSR threshold and BA threshold is higher in severe-profound sensorineural deafness children. (2) The hearing test combination can evaluate the residual hearing ability for children with severe hearing loss.

With homology cloning approaches coupling with RACE (rapid-amplification of cDNA ends) techniques, the full-length coding sequence of pathogenesis-related protein PR10-1 with differential expression was cloned from the total RNA of the root of Panax notoginseng, and its function was explored furtherly. As a result, the longest 465 bp ORF (named as PnPR10-1 with the Accession No. KJ741402 in GenBank) was detected from the cloned sequence with full-length of cDNA of 863 bp. The corresponding peptide encoded consisted of 155 amino acids, contained some domains such as Bet-v-I, and showed high similarity with that from Panax ginseng by analysis of phylogenetic trees created from the alignments. Real-time quantitative PCR showed that the expression of PnPR10-1 gene was constitutive in different tissues of 1-3 year old plant, suggesting that it might be involved in growth, development, and secondary metabolism; yet it was up-regulated significantly with the infection of Fusarium oxysporum in root, suggesting that it might be involved in defense against many diseases including root rot in P. notoginseng.

Aim To investigate the protective effect of flavonoids from Radix tetrastigmae (RTFs)on lipopo-lysaccharide (LPS)induced acute lung injury (ALI) of aged mice and the mechanism.Methods Aged C57BL/6J mice were bronchially instillated LPS to in-duce ALI.RTFs were orally administered to treat ALI. After 3 days,bronchoalveolar lavage fluid (BALF) was collected to enumerate leukocytes with Wright-Gi-emsa staining,and to detect inflammatory cytokines with ELISA.ELISA and Western blot methods were al-so used to detect the expression of MAPKs and NF-κB in lung tissues.The activity of NF-κB in nucleic pro-tein extract was detected with TransAMkit.Results
ALI models were successfully induced through LPS in-stillation.RTFs significantly reduced leukocyte,espe-cially neutrophil infiltration in BALF,inhibited IL-1 β, IL-6,IL-1 2p40,TNF-αand sTNF-R1 secretion,and improved pathohistological change of lung tissues.Be-sides,RTFs significantly attenuated the phosphoryla-tion of p38MAPK,NF-κB and the activity of NF-κB. Conclusion RTFs inhibits LPS-induced ALI through p38MAPK and NF-κB pathway and exhibits significant anti-inflammation effect on aged mice.

Objective To investigate changes in serum levels of Th22 cell ? related cytokines and complements in patients with drug eruption before and after treatment, and to explore their possible roles in the occurrence and development of drug eruption. Methods This study included 35 patients with drug eruption, and 35 sex?and age?matched healthy controls. Five milliliters of peripheral blood samples were collected from the controls and patients before and after treatment. Enzyme?linked immunosorbent assay(ELISA)was performed to measure serum levels of interleukin 22(IL?22)and IL?13, and the cytometric bead array(CBA)system was used to determine serum levels of tumor necrosis factor?α(TNF?α) and complement components C3a, C4a and C5a. Results Before treatment, the patients with drug eruption showed significantly higher serum levels of IL?22(40.85 ± 14.56 vs. 29.09 ± 8.66 ng/L, t=5.549, P<0.05), IL?13(869.94 ± 463.39 vs. 372.92 ± 151.75 ng/L, t=6.071, P<0.05), TNF?α(1.03 ± 0.64 vs. 0.44 ± 0.31 ng/L, t=4.321, P<0.05), complement C3a(55.21 ± 32.98 vs. 42.44 ± 14.26 ng/L, t=2.832, P<0.05), C4a(285.11 ± 123.91 vs. 237.00 ± 63.57 ng/L, t=2.257, P<0.05), and C5a(279.68 ± 127.72 vs. 215.98 ± 65.38 ng/L, t=2.495, P<0.05)compared with the controls. After treatment, the serum levels of IL?22, IL?13, TNF?α, complement C3a, C4a and C5a in patients decreased to(32.72 ± 11.77)ng/L,(456.21 ± 123.22)ng/L,(0.64 ± 0.39)ng/L,(45.47 ± 21.11)ng/L,(241.86 ± 84.12)ng/L and(239.61 ± 103.51)ng/L respectively, with a significant difference between the pretreatment and posttreatment values of these proteins(t = 4.443, 5.197, 3.572, 3.213, 2.728 and 4.772, respectively, all P ≤ 0.01). Additionally, the serum levels of IL?22 and IL?13 were still significantly higher in the patients than in the controls(both P < 0.05), while there were no significant differences in the serum levels of TNF?α, complement C3a, C4a or C5a between the patients and controls after treatment(all P > 0.05). Correlation analysis showed positive correlations between complement C3a and C4a serum levels(r = 0.660, P < 0.05), between C3a and C5a serum levels(r = 0.404, P < 0.05), between C4a and C5a serum levels(r = 0.501, P < 0.05), and between IL ? 22 and TNF ? α serum levels(r = 0.573, P = 0.005), but negative correlations between IL ? 22 and complement C3a serum levels(r = -0.490, P = 0.005), in patients before treatment. Conclusion The activation of Th22 cell?related cytokines and complements may play important roles in the occurrence and development of drug eruption, and IL?22 may participate in the regulation of complements.

Objective To profile the omp1 genotypes of Chlamydia trachomatis (Ct) in patients with nongonococcal urethritis (cervicitis) in Guangzhou region. Methods Swab samples were obtained from the urethra of males and cervix of females in clinical settings of venereology and gynecology as well as at outreach sites for the prevention and control of sexually transmitted diseases (STDs). DNA was extracted from the swabs and nested PCR was performed to amplify the variable domain (VD) 1 - 3 of omp1 gene of Ct followed by gene sequencing. The genotypes of Ct were determined based on the amino acid mutation in VD 1 - 2 of omp1 gene. Results Totally, 1208 swabs were collected. Of them, 132 were Ct positive, and 130 positive samples underwent genotyping. Ten ompl genotypes were determined in total, including serotype E (38, 29.23%), D (25, 19.23%), J(24, 18.46%), F(21, 16.15%), G(7, 5.38%), H(5, 3.85%), K(5, 3.85%), B(2, 1.54%), Ja (2, 1.54%), I (1, 0.77%). E, D, J and F were the dominant type of Ct in this region, and amounted to 83% of all the Ct isolates. Mutations were observed within VD 1 and 2 of omp1 gene in serotype D, B and K.Serotypes were undetermined for Ct in 2 patients with mixed infection. Conclusions In Guangzhou region, E,D, F and J are the predominant genotypes of Ct, and amount to 83% of all the Ct isolates. Ct serotype B is also observed in the urethra of males and cervix of females in this region.
