Objective To design an ECG Holter system based on wireless data communication. Methods The system utilized low power microcontroller MSP430F149 to achieve wireless data transmission by module MC35I. ECG data which stored temporarily in SD card were transmitted in the form of SMS through wireless networks. The received messages were converted into intact files of ECG by data integration. Results It realizes ECG playback, analysis and can send messages automatically to inform relatives and doctors. Conclusion The preliminary clinical application indicates that the Holter has stable performance and strong anti-interference ability, and especially suitable for critical patient care.

Purpose To discuss changes of macular choriocapillaris hemodynamics in AMD. Methods Eighty six eyes of 86 patients underwent ICGA,including macular drusen in 15 eyes of 15 patients,exudative AMD in 52 eyes of 52 patients,atrophic AMD in 19 eyes of 19 patients,for the observation of macular choriocapillaris perfusion. Results Choriocapillaris filling phase (CFP) of exudative AMD was obviously longer than that of eyes with normal, atrophic AMD and drusen groups ( P

Objective To verify the applicable significance of confocal scanning laser retinal tomography in age-related macular degeneration (AMD). Methods Heidelberg confocal scanning laser tomography was used to measure 75 eyes of 59 patients with AMD, including 25 eyes of 20 patients with exudative AMD, 25 eyes of 16 patients with atrophic AMD , and 25 eyes of 23 patients with macular drusen. The differences of the width, volume and maximum height of Z profile signal of macula were analyzed. Results Z profile signal width in macular tomography of exudative AMD was wider than that of macular drusen; maximum height and volume in macular tomography of exudative AMD were larger than that of macular drusen (P

ObjectiveTo observe and estimate the image characters of indocyanine green angiography (ICGA) and fundus fluorescein angiography (FFA) in atrophic age-related macular degeneration(AMD) and macular drusen.MethodsFFA, ICGA and fundus photography were performed on 95 eyes of 73 atrophic AMD patients, including 19 patients (26 eyes) with depigmentation and atrophy of retinal pigment epithelium (RPE), 15 (30 eyes) with macular drusen, and 39 (39 fellow eye) with unilateral exudative AMD. ResultsIn 26 eyes with depigmentation and atrophy of RPE, the result of FFA of 24 eyes with depigmentaion showed patch hyperfluorescence, and of ICGA showed patch hyperfluorescence and hypofluorescence on the late photographs; in 2 eyes with maplike atrophy of RPE, the result of FFA showed patch hyperfluorescence, and of ICGA showed choriocapillaris defect with sharply demarcated boundaries and hypofluorescence of large choroidal vessels. In 30 eyes with macular drusen, the result of FFA of 8 eyes with hard drusen showed hyperfluorescence, and of ICGA showed patch and spot hyperfluorescence; the result of FFA of 16 eyes with soft drusen showed hyperfluorescence, and of ICGA showed persistent patch hypofluorescence intermixed with cluster hyperfluorescence; and the result of FFA of 6 eyes with both soft and hard drusen showed hyperfluorescence, and of ICGA showed patch hyperfluorescence intermixed with hypofluorescence. When it was hypofluorescence in ICGA in patients with macular drusen, larger quantity and range of fluorescence were found in FFA than in ICGA; when it was hyperfluorescence in ICGA, smaller quantity and range of fluorescence were found in FFA than in ICGA. In 39 fellow eyes of unilateral exudative AMD, 32 or 31 eyes, examined by ICGA or FFA, had abnormal fluorescence of drusen and depigmentation and atrophy of RPE damage.ConclusionsSimultaneous examination of ICGA and FFA can be useful for accurate evaluation of fundus image characters of types of angiography in atrophic AMD.

Breast cancer has become the most common malignant tumor and the major cause of cancer-related death for women around the world. The number of patients shows an increasing trend recently. Breast cancer is a big threaten to wom?en’s health and quality of life. With the development of molecular biology, molecular biomarkers have been found assiciated with prognosis in patients with breast cancer, which makes it possible to predict cancer patient survival precisely and practi?cally. This review summarized those new developments of biomarkers on the prognosis of breast cancer.

Objective To investigate the in vitro effect of multi glycosidorum triptery (MGT) on cytokine production by splenocytes of oxazolone (OXZ) induced colitis in murine model. Methods Six mg of OXZ (in 50% of ethanol) was administered in male SJL/J mice intrarectally to induce colitis and mice were sacrificed 3 days later. Isolated splenocytes were cultured for 24 hours in the presence of PMA and ionomycin, MGT of 0.1 mg/ml or 0.01 mg/ml was added to the culture medium of splenocytes. Production of IFN ? and interleukin 4 (IL 4) in the supernatant was measured by ELISA. Results The production of IFN ? was suppressed by both 0.01 mg/ml and 0.1 mg/ml of MGT [normal control ( 1.24 ? 0.13 ) pg/ml→(0.97?0.26) pg/ml→(0.87?0.18) pg/ml, P

Objective To discuss the image of indocyanine green angiography (ICGA) about high myopia. Methods Tweenty seven patients (54 eyes) with high myopia underwent ocular examination, fundus color photography, simultaneous ICGA and fluorescein angiography (FFA) with the confocal scanning laser ophthalmoscope.The findings for the two modes of amgiographies were compared. Results Lacquer crack was evident on ICGA in 19 eyes among which the focal, plaque choroidal neovascularization (CNV) were apparent in the middle part of lacquer cracks in 10 eyes (52.6%) .In comparison the lacquer cracks were seen in only 7 eyes on FFA. Choroidal capillary atrophy was seen on ICGA and FFA in 14 eyes and ICGA shew thick choroidal vessels in 3 eyes. Conclusion ICGA is superior to FFA for showing choroidoretinal degeneration and atrophy,lacquer crack and CNV in high myopic eyes, and conduce to evaluating prognosis.

The relation between patent applications and published papers in hospitals of Guangdong Province since 2000 on China Intellectual Property Network was analyzed , which showed that the quality and quantity of patents were lower in hospitals of Guangdong Province than in those of Shanghai and Beijing , the quality of patents was re-lated with the medical service level in hospitals, the patent applications were centralized in large class A hospitals of Guangzhou , and inventive patents were those of medical preparations .Suggestions were thus put forward for hos-pitals of Guangdong Province to improve their awareness of patent application, the quality of patents, transformation of patents, cooperation with patent service organizations, research of patent application, and balance of patent dis-tribution in different areas.

RNA-Sequencing (RNA-Seq) is a newly-developed method in transcriptome research, it can afford more accurate transcription information and be more quickly by using Next-generation Sequencing (NGS) technology. RNA-Seq has been widely used in various biological fields. Genuine traditional Chinese medicines (TCM), with good quality and therapeutic effect, were always praised highly and used by famous physicians. The geo-herbalism formation of TCM is based on the product of the gene expression at specific space and time. So it has been a research hotspot to analyze the mechanism of biosynthesis through RNA-Seq in the study on the secondary metabolism of medicinal plant. This article mainly illustrates the RNA-Seq and its advantages, it also discusses the potential application in genuine TCM, and it can provide useful information for other researchers.
