ABSTRACT

Objective:To evaluate the effectiveness and feasibility of health management based on cloud platform for population with high-risk of coronary heart disease (CHD).Methods:In this study, self-control method was used to study the high-risk group of CHD in two community outpatient clinics in Jinshui District, Zhengzhou through cloud platform. One year later, the clinical indicators, the degree of mastering CHD prevention knowledge andthe medicine compliance of the group were evaluated. Finally, the feasibility and acceptance of cloud platform management were evaluated through questionnaire survey.Results:A total of 272 people were enrolled intothe group. After one year of cloud platform management, the blood lipid, uric acid, homocysteine and fasting blood glucose in the group weresignificantly improved (all P<0.05), but the glycosylated hemoglobin was not significantly reduced [(6.4±1.2)% vs.(6.3±1.1)%, P>0.05]. The degree of mastering CHD prevention knowledgewas significantly improved, and the medicine compliance was not significantly improved [(5.0±1.6) vs. (5.0±1.5), P>0.05]. Questionnaire survey showed that 228 (83.8%) of the patients had a high acceptance of cloud platform management, and 208 (76.5%) of the group wanted to continue to use cloud platform for health management. Conclusions:Health management based on cloud platform can improve the clinical index control of the high-risk population of CHD, and help the high-risk population to master the relevant knowledge of CHD prevention. Some functions of cloud platform need to be further improved.

ABSTRACT

Objective To investigate the partial safety of the recombinant adenovirus containing the triple-point mutants HIF-1αgene (Ad-HIF-1α-Trip)transfection in a rabbit model of hind limb ischemia. Methods After ligation of left femoral artery, 22 New Zealand whites rabbits were randomly divided into 3 groups: saline group(n=6), Ad-Null group(n=6) and Ad-HIF-1α-Trip group(n=10). After operation, saline, Ad-Null and Ad-HIF-1αwere injected intramuscularly respectively. The expression of transferred HIF-1αat mRNA level in the ischemic skeletal muscle and other important organs were detected by Real-time PCR 10 days after gene transfection. The body temperature, weight, blood, liver and renal function, as well as the myocardial enzymes were detected before operation, and on the 3th, 7th, 14th and 28th day after gene transfection, so that pathological changes could be observed. Results On the 10th day after gene transfection, obvious expressions of HIF-1αat mRNA level in the ischemic limb were found, but no expression in other important organs was detected in Ad-HIF-1α-Trip group. The blood routine, liver and renal function were all in the normal range (P > 0.05). No abnormalities were found in heart, liver, kidney, and lung HE transfection in Ad-HIF-1α-Trip group. Conclusion Single intramuscular injection of Ad-HIF-1α-Trip can be expressed obviously in the ischemic limb without detected damage of liver , cardiac and kidney.

ABSTRACT

Triple X syndrome is a sex chromosomal aneuploidy condition characterized by tall stature, microcephaly, hyperteloris, congenital abnormalities, and motor and language delays. It is mainly derived from maternal nondisjunctional errors during meiosis. To highlight the clinical features and diagnosis of triple X syndrome, we present a rare phenotype of the syndrome. A 5.9 year-old girls was admitted to our hospital because of short stature. Both her height and weight were below the 3[rd] percentile compared to the normal peers. She was found with mild motor and speech delay. Laboratory investigation showed low level of IGF-1 and zinc, elevated estradiol level and normal result of arginine provocation test. Our data suggest that triple X syndrome should also be suspected in patients with short stature, elevated estradiol and low level of IGF-1, even with normal result of arginine provocation test

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the effects of a recombinant adenovirus-mediated triple mutant hypoxia-inducible factor-1α (HIF-1α) on the proliferation and vascular endothelial growth factor (VEGF) expression in human microvascular endothelial cells (hMVECs).</p><p><b>METHODS</b>The adenovirus vector of the triple mutant HIF-1α (Ad-HIF-1α(564/402/803)), adenovirus vector of wild-type HIF-1α (Ad-HIF-1α(nature)), Ad-lacZ and Ad-Null were amplified in HEK293A cells, and the adenoviruses were purified and titrated. Dual luciferase reporter assay system was employed to detect the transcriptional activities of wild-type and triple mutant HIF-1α. After infection of the hMVECs with the adenoviruses, the cellular protein expressions of HIF-1α and VEGF were detected using Western blotting, and the cell proliferation was assessed by MTS assay.</p><p><b>RESULTS</b>The transcriptional activity of the triple mutant HIF-1α was significantly higher than that of wildtype HIF-1α in the infected hMVECs (P<0.001). The protein levels of HIF-1α and VEGF in cells infected with Ad-HIF-1α(564/402/803) were significantly higher than those in cells infected with other adenoviruses, and HIF-1α dose-dependently up-regulated VEGF protein expression. The absorbance was significantly higher in Ad-HIF-1α(564/402/803) group than in the other groups (P<0.01) on the third and fifth days after infection.</p><p><b>CONCLUSION</b>The recombinant adenovirus-mediated triple mutant HIF-1α expression is stable under normoxic condition. The triple mutant HIF-1α can up-regulate the expression of VEGF protein in hMVECs to promote the cell proliferation.</p>

ABSTRACT

Experimental autoimmune encephalomyelitis (EAE) is an autoimmune disease of the central nervous system (CNS); it serves as a model for the human multiple sclerosis (MS). In mice, EAE is mediated by T cells specific for various myelin basic proteins which migrate from the periphery to the CNS. In search of a way to prevent the induction and progression of EAE, we observed the effects of recombinant immunotoxin IP10-DT390 on blocking or eliminating the active T cells in the EAE model. In this paper is presented an experimental gene therapy-based model in which the mice were made resistant to EAE induction by plasmid DNA encoding recombinant immunotoxin that was injected into the leg muscles of mice. The new immuno-biological construct could selectively impair autoreactive T-cell homing while the duration of clinical signs is shorter, and the new construct would not affect other components of the immune response. These data demonstrated the effectiveness of the constructs in the treatment of EAE and suggested its usefulness in the treatment of other autoimmune diseases.
