Objective To investigate the possible role of leukocytes, a important cellular component of the blood, in the induction of microcirculatory disturbances in noise-exposed cochleae. Methods Guinea pigs were exposed to a 4 kHz narrow band noise at 115 dB SPL for 4 hours, and the exposed cochleae were collected at 2 or 4 days after the noise exposure. Several techniques (cell viability assay, fluorescent labeling for blood plasma and for hair cell nuclei) were used to examine morphological changes in microvessels in the spiral lamina and in the stria vascularis as well as the hair cell nuclei. Results In noise-exposed cochleae, aggregatad leukocytes were found in the vessels of the spiral lamina. In the up-stream of the vessels with aggregated leukocytes, red blood cells were tightly packed, causing an increase in vessel diameters. Most leukocytes were located within the lumen of vessels, but some of them infiltrated the spiral lamina, usually alongside the vessels. Cell viability, assessed by trypan blue staining, showed that these plugged leukocytes lost their viability. In contrast, no leukocytes aggregated in the vessels of the stria vascularis, nor did leukocytes lose their viability. Conclusion In the cochleae exposed to intense noise, leukocytes were trapped in the vessels of the spiral lamina, leading to disturbance of blood flow. The involvement of leukocytes in local damaging processes and the fate of leukocytes need further studies.

Objective To evaluate the clinical safety and efficacy of Cheatham-Platinum(CP)covered stent in treatment of aortic coarctation.Methods The therapeutic efficacy was retrospectively analyzed in 15 patients with aortic coarctation who were treated by BIB balloon dilation and CP covered stent implantation.Results All patients were well recovered,the stent did not appear displaced,folded,aorta dissection and rupture.The pressure difference was 5-10 mm Hg(1 mm Hg=0.133 kPa)between proximal part and distal end after operation.Following up(20±12)months,the therapy efficacy of all the patients was stable and there was no fracture,removal,aortic stenosis or dysarteriotony.Heart ultrasounds demonstrated good close of the cases with patent ductus arteriosus.Conclusion CP covered stent is a safe and available clinical therapy,featured by minimum aorta injuries.

To observe the morphological changes in hair cell nuclei in guinea pigs following noise exposure, guinea pigs were exposed to 4 kHz narrow band noise at 115 dB SPL for 4h. The cochleae were collected for the examination of the hair cell nuclei 14 days after the noise exposure. A fluorescent dye, Hoechst 33342,a fluorescent dye, was used to label the nuclear DNA and the specimens were examined under a fluorescence microscope for quantitative assessment of hair cell nuclear damage. There were three types of morphological changes in the damaged hair cell nuclei: nuclear swelling, nuclear condensation (karyopyknosis) and nuclear missing. Nuclear swelling was more frequent than nuclear missing. Nuclear condensation was less frequently found. The results suggested that complicated, long term and non synchronous biological processes might be involved in noise induced hair cell damage. A large number of hair cells with swollen nuclei, which might recover afte wards,still could be seen in the cochlea two weeks after noice exposure.

Objective To investigate the expression of Smad5 gene in the cochlea and to identify its location. Methods Reverse transcription polymerase chain reaction (RT-PCR) was employed to detect the expression of Smad5, the in situ hybridization and the immunohistochemical technique were used to localize the Smad5 messenger RNA and the Smad5 protein in mouse cochlea. Results Smad5 gene expressed in cochlea at a high level. Smad5 expression was concentrated in supporting cell, hair cell, spiral ganglion, epithelium of stria vascularis and basilar membrane. Conclusion The Smad5 proteins exist in the mouse cochlea and it may be involved in the cochlear formation and the differentiation of hair cell. Smad5 might be an essential factor for the development of normal cochlea.

Epidemiological surveys show that folic acid can prevent prostate cancer, but fortified folic acid may increase the risk of the malignancy. The physician data queries from the National Cancer Institute of the USA describe folate as protective against prostate cancer, whereas its synthetic analog, folic acid, is considered to increase prostate cancer risk when taken at levels easily achievable by eating fortified food or taking over-the-counter supplements. We review the current literature to examine the effects of folate and folic acid on prostate cancer, help interpret previous epidemiologic data, and provide a clarification regarding the apparently opposing roles of folate for patients with prostate cancer. A literature search was conducted in Medline to identify studies investigating the effect of nutrition and specifically folate and folic acid on prostate carcinogenesis and progression. In addition, the National Health and Nutrition Examination Survey database was analyzed for the trends in serum folate levels before and after mandatory fortification. Folate likely plays a dual role in prostate carcinogenesis. There remains some conflicting epidemiologic evidence regarding folate and prostate cancer risk. However, there is growing experimental evidence that higher circulating folate levels can contribute to prostate cancer progression. Further research is needed to clarify these complex relationships.
