BACKGROUND:L-type calcium channels, as a kind of voltage-dependent calcium channel, is the main way of extracellular calcium ions into the cell, and play an important role in maintaining cellmorphology and physiological activities, characterized by a large single-channel conductance, slow channel attenuation, and longer duration of channel opening. Previous studies showed that basic fibroblast growth factor can promote the proliferation of chondrocytes cultured in vitro.
OBJECTIVE:To explore the effect of the L-type calcium channels on regulating chondrocyte proliferation and differentiation in response to basic fibroblast growth factor with patch-clamp.
METHODS:The chondrocytes were harvested from the joints of 3-day-old New Zealand rabbits. The second passage of chondrocytes was divided into experimental group and control group. Chondrocytes were incubated in media containing 10μg/L basic fibroblast growth factor and media alone separately. The opening of L-type calcium channels under the action of basic fibroblast growth factor was detected by patch-clamp. The intracellular calcium concentration was detected with laser confocal microscopy in the chondrocytes after 2 weeks of culture with basic fibroblast growth factor. Chondrocyte proliferation was analyzed by cellTiter kit after 8 days of culture. Type Ⅱ col agen was assessed quantitatively by immunohistochemistrical staining after 10 days of culture.
RESULTS AND CONCLUSION:Basic fibroblast growth factor has an inhibitory effect on the opening of the L-type calcium channels, resulting in a decrease in intracellular free calcium concentration (P<0.01). cellnumber was higher after culture with basic fibroblast growth factor than that cultured under conventional condition (P<0.01), and staining area of type II col agen significantly increased (P<0.05). Results verified that basic fibroblast growth factor can maintain intracellular Ca2+concentration at a low level by inhibiting the opening of L-type calcium channels, which can promote the proliferation and differentiation of chondrocytes.

Objective To measure and compare the expression profdes of plasma miRNA between Tibetan and Han nationality.Methods Plasma samples were taken from 246 healthy Tibetans and 128 Han individuals.The randomly selected 50 Tibetan and Han plasma samples were pooled respectively and the levels of 754 miRNAs were examined using a TaqMan Low Density Array.Two markedly differentially expressed miRNAs,miR-130a-3p and miR-629-5p,were verified in all the plasma samples by individual qRT-PCR.Results The Low Density Array results showed that the correlation coefficient of expression profiles of plasma miRNA for the Tibetan and Han population was 0.592.Compared with Han population,the expression levels of 139 miRNAs were distinctly different,in Tibetan (62 up-regulated and 77 down-regulated).The levels of miR-130a-3p and miR-629-5p were further verified to be significantly higher in the plasma from Tibetans than those in the plasma from Han population [(467 ± 27.30) × 10-5 vs (236 ± 9.69) × 10-5,p ＜ 0.01;(14.67 ±0.94) × 10-5 vs(7.58 ± 0.52) × 10-5,P ＜ 0.01] by qRT-PCR assay.Conclusion There may be marked difference of plasma miRNA expression profile between Tibetan and Han nationality.The influence of the nationality factors on miRNA profiles should be taken into account in the application of miRNAs in clinical detection in the future.

Objective To explore the effectiveness of KAP-HBM-TTM(KHT)-based health management on patients with chronic diseases in community. Method From April 2014 to June 2015, 834 patients with chronic diseases living in Desheng Community were randomly sampled and assigned to the intervention group (n=423, and the control group n=411). The K-H-T mode was used for the intervention group, and the routine management mode was applied to the control group. Using self-made questionnaire we tested two groups of patients' knowledge, attitude and life-style behavior. Chi-square test was used for data analysis. Result After one year KHT-based health management, the proportion of patients with reaching the standard knowledge such as diagnosis based, risk factors, correct treatment method, life-style for prevention of chronic disease and regular check-up of the intervention group (84.9%, 88.0%, 95.2%, 89.6%, 96.9%) obviously raised compared with the control group (56.3%, 53.6%, 59.5%,55.8%, 62.7%), and the difference was statistically significant (? 2=81.270, 118.394, 155.166, 119.672, 150.173,P<0.05). The proportion of patients with reaching the standard attitude such as on the importance of chronic diseases, the family doctor service, the nurses' health management and changing risk factors of the intervention group (80.8%, 78.2%, 81.8%, 77.5%) obviously raised comapred with the control group (59.0%, 54.3%, 52.8%, 56.5%), and the difference was statistically significant (?2=46.573, 52.429, 78.435, 40.744,P<0.05). The proportion of patients with reaching the standard life-style behavior such as diet, physical exercises, psychological states, correct medication, monitoring blood pressure and glucose of the intervention group (76.7%, 72.2%, 90.6%, 99.3%, 86.1%,42.0%) obviously raised than the control group (30.9%, 30.6%, 58.0%, 73.1%, 57.5%, 28.9%), and the difference was statistically significant (? 2=174.142, 142.147, 115.318, 119.783, 83.164, 15.341,P<0.05). The rate of blood pressure and glucose control of the intervention group (84.2%, 74.8%) also improved as compared with the control group (74.3%, 60.0%), and the difference was statistically significant (? 2=11.598, 20.576,P<0.05). Conclusion KAP-HBM-TTM (KHT)-based health management was proved to be effective in the control of chronic diseases of community and improve the effectiveness of the management.
