Objective To define the expression of AQP4 in normal rat eyes at transcriptional and translational level, so as to provide morphological bases for the mechanisms of water transport in eyes. Methods Immunohistochemical SABC method and in situ hybridization were used to detect the expression and localization of AQP4 in normal rat eyes. Results The corneal epithelium, the iridal pigment epithelium cells, the nonpigment epithelium cells of ciliary body, the lens epithelium cells, the lens fiber cells, the outer nuclear layer cells, and the inner nuclear layer cells, the ganglion cells of the retina showed positive immunoreactivity of AQP4. The reactive substance was distributed in membrane but not in nuclei of all positive cells. The resuIts of in situ hybridization were identical with that of immuohistochemistry method. AQP4 mRNA could be detected in the cytoplasm of positive immunoreactive cells, however, nuclei were negative. Conclusion The results implied that AQP4 could coordinate with other AQP4 to play an important role in the secretion and regulation of aqueous humor, the maintenance of the diaphaneity of cornea and lens, the motivation and transmission of optesthesia.;

OBJECTIVE To study the therapeutic effect of ceftazidime(CAZ) in a rat model of pneumonia caused by CTX-M-14 extended-spectrum ?-lactamases(ESBLs)-producing Klebsiella pneumoniae which is susceptible to ceftazidime in vitro.METHODS Forty eight rats were divided into four groups randomly which were ceftazidime-treated group,piperacillin/tazobactam-treated group,ceftaxime-treated group and the control group.All rats were intranasally inoculated with bacterial suspension of CTX-M-14 ESBLs-producing K.pneumoniae to produce pneumonia models.Twenty four hours after inoculation,rats were intramuscularly administered ceftazidime,piperacillin/tazobactam,ceftaxime,or saline,respectively.The temperature,leucocyte count,percentage of neutrophils,and bacterial counts in the right lungs of rats were detected at some timepoints.RESULTS Compared with the ceftaxime-treated group and the control group,the leucocyte count,percentage of neutrophil count and common logarithm of the bacterial count in the right lungs of the ceftazidime-treated group and piperacillin/tazobactam-treated group after the treatment which lasted seventy two hours were significantly lower than those of ceftaxime-treated group and the control group(P0.05).CONCLUSIONS Ceftazidime shows good therapeutic effect in pneumonia in rats caused by CTX-M-14 ESBLs-producing K.pneumoniae which is susceptible in vitro.

This paper briefly introduced the characteristics, origin and development of virtual reality, and the value for rehabilitation; reviewed the application of virtual reality in the rehabilitation of balance function after stroke. Some assessment commonly used for balance function were summarized.

OBJECTIVETo observe the efficacy of encephalopathy therapeutic tongue acupoint apparatus (ETTAA) in the treatment of autism.

METHODSEighty-four children of autism were randomly divided into a tongue acupuncture group (group A) and a conventional training group (group B), 42 cases in each group. The behavior training and sensory integration training were carried out in group B and the ETTAA was added in group A. The apparatus was switched on for 20 min every time and 3 times a day. Treatment of two months were carried out in both groups. The score of childhood autism rating scale (CARS) and clinical efficacy in both groups were observed before and after treatment.

RESULTSAfter treatment, the CARS in both groups were significantly reduced (42.39 +/- 6.86 vs 32.15 +/- 5.12, P < 0.001; 44.58 +/- 6.76 vs 39.72 +/- 7.11, P < 0.05), which was more significant in group A (P < 0.01). The totally effective rate in group A [90.5% (38/42)] was superior to that in group B [66.7% (28/42), P < 0.01].

CONCLUSIONThe clinical efficacy in tongue acupuncture group is apparently superior to that in conventional training group, ETTAA combined with conventional training have a better curative effect in the treatment of autism.

OBJECTIVETo analyze the status and papers information of Chinese Journal of Applied Physiology, and provide a guide for authors, readers and editing staffs.

METHODSWe retrieved papers of Chinese Journal of Applied Physiology from 2009 to 2013 from CNKI, and performed a statistical analysis of papers information contained in the text using bibliometrics method. Papers information such as document type, found support, author affiliation type, and discipline classification, etc. was analyzed.

RESULTSSeven hundred and forty two papers including 27 full English articles in total were published in Chinese Journal of Applied Physiology from 2009 to 2013. More papers were supported by national, provincial, and the other foundation, it was about 82.6% of all papers.

CONCLUSIONChinese Journal of Applied Physiology has stable manuscript resources, various discipline papers, and play an important role for development of applied physiology in China.

Tumor is a complex systemic disease, involving abnormalities at multiple levels, such as DNA, RNA, protein and metabolite. According to the central rule, the derived omics methods are genomics, transcriptomics, proteomics and metabonomics. In the past few decades, there have been remarkable achievements in the single omics study of tumor, but the exact mechanism of tumor development is still unclear. In order to reveal the process of tumorigenesis and development in a more systematic way, the research of multiomics came into being, which promoted the transformation of tumor research paradigm from single parameter model to multi parameter system model. The integration of multi-omics methods is expected to clarify the mechanism of tumor occurrence and development, find biomarkers with diagnostic, prognostic and predictive performance, explore new treatment targets, and finally achieve predictive, preventive, and personalized medicine (PPPM). This paper reviews the research methods and progress of different omics techniques in tumor research, especially emphasizes the importance and scientific value of the integration of multiple omics techniques in tumor research and clinical related results.

Objective To evaluate the value of helical CT and pulmonary artery angiography in the diagnosis and treatment of pulmonary embolism. Methods The data of helical CT and pulmonary angiography of 18 cases of pulmonary embolism suspected by clinical diagnosis were analyzed retrospectively. Pulmonary embolism was diagnosed in 12 patients with pulmonary angiography, and treated by suction throngh cathether and local fibrinolysis. Results Embolism was found to involve 107 pulmonary artery branches in the 18 cases, including bilateral pulmonary lower lobes in 28.97%, left and right main pulmonary artery in 22.43%, lobar artery and segmental artery in 40.18%, and main pulmonary artery in 8.41%. The direct signs of helical CT and pulmonary angiography included partial filling defect, mural filling defect, central filling defect or so-called railway-track sign, and total occlusion. Secondary signs included enlargement of pulmonary artery trunk, local pulmonary digemia, pulmonary infarction and pleural effusion. 12 patients survived and showed clinical improvement with significant increase in PaO_2. Conclusion Helical CT is a noninvasive and effective method for the diagnosis of pulmonary embolism, while the pulmonary artery angiography is also an important tool in diagnosis and treatment of it.

Objective To localize the gene of a Chinese autosomal-dominant non-syndrome deafness (DFNA) family by linkage analysis. Methods Pedigree was drawn after genetic investigation. All family members were checked up, and detail audiology examination proceeded (including pure tone audiometer, acoustic immittance measurement, auditory brainstem response). Vestibular function was evaluated. At first, the similarity of the family's locus linkage with the known DFNA loci should be excluded, and then whole genome scan was carried out. Results Deafness gene of this family was localized at 2q13-q14.2. A maximum LOD score of 3.22 (?=0.00) was obtained with the microsatellite marker D2S363. Haplotype analysis placed the novel locus within a 8.4cM region interval defined by markers D2S1888 and 2S2224. DNA sequencing of coding regions and exon/intron boundaries of a candidate gene PAX8 in this interval did not reveal disease-causing mutation in this family. Conclusion A novel DFNA locus was defined in a Chinese Neimeng family.
