OBJECTIVETo investigate the effects of salvia miltiorrhiza injection (SM) on gentamicin (GM)-induced expression of nitric oxide synthase (NOS) isoforms in guinea pig cochlea, and to explore the protective mechanism of SM on GM-induced ototoxicity.

METHODS40 guinea pigs were randomly assigned to 4 groups: control group, GM group, SM group and GM plus SM group. Expression of NOS isoforms in the guinea pig cochlea was detected by the SABC method of immunohistochemistry and microscope image analysis technique. Auditory threshold was tested by auditory brainstem response (ABR) measurement.

RESULTSInducible NOS (iNOS/NOS II) expression and ABR threshold in GM plus SM group were both significantly declined as compared with those in GM group (P < 0.01). Moreover, change of iNOS expression was in high correlation with that of ABR threshold ([r] > 0.7, P < 0.01). While expression of neuronal NOS (nNOS/NOS I) and endothelial NOS (eNOS / NOS III) showed no significant differences in all groups.

CONCLUSIONSM had no effect on the expression of nNOS and eNOS, but could inhibit iNOS high-expression induced by GM to reduce excessive generation of NO, therefore SM could protect against GM ototoxicity.

Psychrotrophs were isolated by using four media from low-temperature sewage of sewage treatment plant in Urumqi, Xinjiang. Totally, 154 strains were obtained including 12 filamentous fungi, 46 yeasts, 6 actinomycetes and 90 bacteria. The results of tolerance tests of the isolates to salt, phenol and SDS, and enzyme producing characters of amylase, proteinase and esterase were shown. Then 60 bacterial strains were chosen for 16S rRNA gene sequencing and analysis. The blasting results showed that the strains were assigned to 13 recognized genera , and the Strain 39 exhibited 96.6% similarity to Acinetobacter lwoffii(DSM2403), indicating that it might be a novel species. These results suggested that there were a lot of psychrotrophs and rich bacterial diversity in low-temperature sewage. In addition, which maybe an important and potential library of microbial resources.

Xanthomonas campestris pv. campestris ( Xcc), causative agent of the black rot disease of cruciferous crops worldwide, produces large amount of extracellular polysaccharide( EPS), which has found wide applications in industry. In order to clone genes involved in EPS biosynthesis, Xcc wild-type strain 8004 was mutagenized with transposon Tn5gus A5, and a number of EPS-defective mutants were isolated. The Tn5gusA5 insertion sites in the mutants were analyzed by using thermal asymmetric interlaced PCR(TAIL-PCR), and the corresponding genes were identified by homology blast to the completely sequenced genome of Xcc 8004 strain. A novel gene, waxE, identified from the EPS-defective mutant 151D09, was found to be disrupted by the insertion of Tn5gusA5 in the open reading frame(ORF) with genome coordinates 4478998bp to 4479819bp.This gene showed 52% similarity to the kdtX gene of Serratia marcescens and 50% to the waaE of Klebsiella pneumoniae at amino acid level, with characteristics of glycostransferase 2 family domain. In order to identify the function of waxE gene, waxE gene deletion mutant of Xcc 8004 was constructed by gene replacement strategy in which waxE gene of genome was replaced by kanamycin resistant gene kan. The waxE gene deletion mutant strain, named Xcc 8570, was confirmed by both PCR and southern analysis. The growth rate of the deletion mutant 8570 in rich medium was not affected, but the EPS yield reduced by 35% as compared with the wildtype strain 8004. The deletion mutant could be completmented in trans with plasmid pLATC8976 harboring an intact waxE gene, and the EPS yield of the mutant was restored. The combined data showed that waxE gene involved in EPS biosynthesis in Xcc.

OBJECTIVEThe pathogenesis of irritable bowel syndrome (IBS), a functional gastrointestinal disorder, is poorly understood. Treatment by Chinese medicine and pharmacy (CMP) is superior to treatment by Western medicine (WM). Therefore, we aimed to analyze Chinese medical experts' experiences in treating IBS by data mining.

METHODSBy retrieving related literatures from 1994 to 2012 from CNKI, we chose proved cases and screened effective medical records to establish a database using structural electronic medical case collecting system and data mining. The thinking ways of modern physicians in diagnosis and treatment of IBS were analyzed.

RESULTSTotally 116 medical cases from 46 Chinese medical experts were recruited and analyzed. Results showed that Gan depression and Pi deficiency were most basic syndrome elements. In addition, cold dampness, damp heat, yang deficiency, and Shen deficiency were main elements for the development of diarrhea predominant IBS (IBS-D). Qi stagnation, yin deficiency, qi deficiency, and blood stasis were main elements for the development of constipation predominant IBS (IBS-C). Soothing Gan-qi and strengthening Pi was the most important treatment method. White peony root, prepared atractylodes, prepared licorice, tangerine peel, poria, bupleurum, Radix sileris, lanceolata, and Radix aucklandiae were the most common Chinese herbs used in treating IBS.

CONCLUSIONS(1) Gan depression and Pi deficiency was the main pathogenesis for IBS. Diagnosis and treatment of IBS should be performed clinically according to its development. Tongxie Yao-fang should be used as the basic prescription with modification according to syndrome differentiation. (2) Data mining will have a wide application prospect in studying medical cases.
