ABSTRACT

Traditional Chinese medicine (TCM) and western medicine have their respective advantages and limitations in the diagnosis and treatment of common otorhinolaryngology head and neck diseases. Although the integrated TCM and western medicine exhibits definite curative effects, there is no consensus on the otorhinolaryngology head and neck diseases responding specifically to TCM or integrated TCM and western medicine, as well as the diagnosis and treatment schemes. The China Association of Chinese Medicine (CACM) thus organized the otorhinolaryngology head and neck specialists of both TCM and western medicine to discuss the etiology, pathogenesis, and clinical diagnosis and treatment methods of common otorhinolaryngology head and neck diseases with the results of multiple clinical trials taken into account. The acute pharyngitis, chronic pharyngolaryngitis, paraesthesia pharyngis, hysterical aphasia, allergic rhinitis, subjective tinnitus, and otogenic vertigo were confirmed to respond specifically to TCM or integrated TCM and western medicine. Then a mutually agreed diagnosis and treatment scheme and recommendation with integrated TCM and western medicine was formulated as a reference for clinical practice, thus benefiting more patients.

ABSTRACT

Objective:The biological mechanism of <italic>Codonopsis pilosula</italic> adaptation to drought was explored by determining the root metabolome of <italic>C. pilosula</italic> during harvesting. Method:Non-targeted metabonomics LC-MS was used to screen differential metabolites by multivariate statistical analysis,univariate statistical analysis and metabolic pathway enrichment analysis. Result:①There were 274 metabolites in LD vs CK group,142 of which were up-regulated and 132 of which were down-regulated. There were 284 metabolites with significant difference in MD vs CK group,of which 157 were up-regulated and 127 were down-regulated. There were 317 metabolites with significant difference in SD vs CK group,of which 133 were up-regulated and 184 were down-regulated. ②Differential metabolites were annotated into kyoto Encyclopedia of Gene and Genomes (KEGG) database and 82 differential metabolic pathways were obtained,among which sphingolipids metabolism was significantly enriched (<italic>P</italic><0.01).Metabolism of arginine and proline,tryptophan,alanine,galactose,nicotinic acid and nicotinamide,cysteine and methionine,arachidonic acid,linolenic acid and glycerides were significantly enriched in different metabolite pathways (<italic>P</italic><0.05). ③The metabolites of the three comparison groups before and after enrichment were classified and analyzed. It was found that they were mainly concentrated in fatty acyls group,carboxylic acid and derivatives,and organ oxygen compounds,followed by sphingolipids,indoles and derivatives,organonitrogen compounds,glycerophospholipids,pyridines and derivatives,peptidomimetics,glycerolipids and so on.In the drought stress of <italic>C. codonopsis</italic>,carbohydrate related metabolites were mainly up-regulated,lipid related metabolites were mainly down-regulated,and all other metabolites were up-regulated. Conclusion:The changes of metabolites in the roots of <italic>C. pilosula</italic> under drought stress were elucidated. carbohydrate and lipid-related metabolites were the main products of <italic>C. pilosula</italic> under drought stress,and these metabolites may be the main reason to improve the ability of <italic>C. pilosula</italic> to resist drought,which laid a foundation for further study on the mechanism of <italic>C. pilosula</italic> to resist drought.

ABSTRACT

OBJECTIVE@#To explore the regulatory effect of TRIP13 on the proliferation and apoptosis of B-cell lymphoma cells and its possible molecular mechanism by knocking down/overexpressing TRIP13 on the cell lines Granta-519 and JVM-2.@*METHODS@#Lentiviral transfection technology was used to construct Granta-519 and JVM-2 cells with knocked down or overexpressed TRIP13 and their control cells. The efficiency of transfection was determined by fluorescence microscopy. The efficiency of knockdown and overexpression was evaluated by real-time quantitative PCR and Western blot. The proliferation was detected by CCK-8 assay. The apoptosis was detected by the Annexin V-APC single staining. The cell cycle was detected by the PI staining. The expression levels of P53, MDM4, and BCL-2 were evaluated by Western blot.@*RESULTS@#After TRIP13 was knocked down, the proliferation ability of Granta-519 and JVM-2 cells was significantly reduced, and the apoptosis rate significantly increased. After TRIP13 was overexpressed, the proliferation ability of Granta-519 and JVM-2 cells was significantly enhanced, and the apoptosis was significantly reduced. After TRIP13 was knocked down, Granta-519 cells had obvious G@*CONCLUSION@#TRIP13 promotes the proliferation of B-cell lymphoma cells, inhibits their apoptosis, and affects their proliferation and apoptosis by participating in the regulation of the cell cycle. TRIP13 promotes the expression of BCL-2 proteins and inhibits the expression of MDM4 protein in B-cell lymphoma cells.

ABSTRACT

The therapeutic effects of endothelial progenitor cells (EPCs) on ischemic stroke have been extensively studied in recent years. However, the differences in early EPCs and endothelial outgrowth cells (EOCs) are still unclear. Clarifications of their respective properties and specific functioning characteristics contribute to better applications of EPCs in ischemic diseases. In this review, we discuss cellular origin, isolation, culture, surface markers of early EPCs and EOCs and relevant applications in neurological diseases. We conclude that EOCs possess all haracteristics of true endothelial progenitors and have potent advantages in EPC-based therapies for ischemic diseases. A number of preclinical and clinical applications of EPCs in neurological diseases are under study. More studies are needed to determine the specific characteristics of EPCs and the relevant mechanisms of EPCs for neurological diseases.

ABSTRACT

AIM:To explore the histopathological classification and incidence of orbital space-occupying lesions in children in order to provide references for the diagnosis of orbital space-occupying lesions in children. METHODS:A total of 290 paediatric patients with orbital space - occupying lesions diagnosed by pathological examinations at the Second Hospital of Tianjin Medical University from January 1998 to December 2012 were retrospectively reviewed. RESULTS:In 290 paediatric patients with orbital space-occupying lesions, venous hemangioma was the most common (58 cases,20. 0%), the other commons were as follows: hemangio lymphangioma, dermid cyst, neurofibroma, optic nerve glioma, rhabdomyo sarcoma and so on. Capillary hemangioma, venous hemangioma, optic nerve glioma had the predominant age incidence. On the other hand, optic nerve glioma, venous hemangioma, rhabdomyosarcoma had the predominant sex incidence. CONCLUSION: The majority of paediatric patients with orbital space - occupying lesions are congenital and embryonic lesions, the most common of which is venous hemangioma. Some lesions had the predominant age and sex incidence.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the difference of transient evoked otoacoustic emissions (TEOAE) between neonates and adults with the frequency-specific approach.</p><p><b>METHODS</b>TEOAE were recorded from 112 newborns (62 females, 58 males) who passed hearing screening, and 32 adults (17 females, 15 males) tested with pure-tone threshold equal or less than 20 dBHL. Band reproducibility, signal-to-noise rate (SNR) of frequency-band and half-octave frequency analysis of TEOAE amplitude was recorded respectively.</p><p><b>RESULTS</b>Significant differences were found in two groups, the higher entire TEOAE level found in newborn [(15.18 +/- 4.39) dB SPL] was higher than that of adults group [(9.51 +/- 4.12) dB SPL, P < 0.05]. The lowest wave reproducibility and SNR were in first frequency band (0.8 kHz) for neonate, and then, in last frequency band (4.0 kHz) were for young adults. For newborns, the highest band reproducibility and SNR were presented at fourth frequency band (3.2 kHz). However, for adults, the highest band reproducibility and SNR were presented at second frequency band (1.5 kHz). Frequency space of the SNR response peaks between neonates and adults was 1.7 kHz. The level difference was 7.09 dB SPL. Half octave frequency analysis shows a TEOAE response peaks in neonates was (10.50 +/- 5.09) dB SPL at the 2828 Hz, and in adults, it was (2.84 +/- 5.33) dB SPL at the 1414 Hz. Frequency space of the TEOAE response peaks between neonates and adults was 1414 Hz. Level differences of TEOAE response peaks was 7.66 dB SPL. TEOAE response peak in adult appear at 1.5 kHz, and then dropped down correlated to increase of frequency. From the first to the last testing frequency band, the difference of TEOAE level between neonate and adult was found to increase correlated to increase of frequency.</p><p><b>CONCLUSIONS</b>TEOAE response level in newborn is higher than that in adult group. Further, the decrease of TEOAE response level presented more sharpens with the frequency increasing in adult. The frequency of TEOAE response peak in neonate (3.2 kHz) is higher than adult (1.5 kHz). The level of TEOAE response peak is also greater than adult.</p>
