BACKGROUND: Chinese medicine Gukang prescription has a clear effect on clinical treatment of osteoporosis, but the therapeutic pathway is stil unclear.
OBJECTIVE:To investigate the effects of Chinese medicine Gukang on the expression of receptor activator of nuclear factor kappa B ligand and osteoprotegerin by regulating core binding factor alpha 1 expression to control the growth and development of osteoblasts.
METHODS:Sprague-Dawley neonatal rats within 24 hours after delivery were used for the separation and culture of osteoblasts. Adult Sprague-Dawley rats were used to prepare drug-containing serum, and then divided into two groups randomly:normal control group and Gukang group. Rats in the normal control and Gukang groups were intragastrical y administrated with extract of Gukang prescription and normal saline based on rat’s body surface area, for 1 consecutive week. Two hours after the last administration, blood samples were taken from the heart. Then the serum was col ected. Osteoblasts at passage 3 were confirmed with alkaline phosphatase assay and digested. After counting and planting, al osteoblasts were divided into two groups and treated with col ected
serum for 72 hours. Proliferative rate of osteoblasts was detected by using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide test. Secretion of alkaline phosphatase was detected by using enzyme linked immunosorbent assay and corrected with the corresponding absorbance value. mRNA expression of core binding factor alpha 1, receptor activator of nuclear factor kappa B ligand and osteoprotegerin were detected by using reverse
transcription-PCR in al groups.
RESULTS AND CONCLUSION:mRNA expression of osteoprotegerin and core binding factor alpha 1 in the Gukang group was significantly higher than that in the normal control group, but protein and mRNA expression of receptor
activator of nuclear factor kappa B ligand were dramatical y lower in the Gukang group compared with the normal control group (P<0.01). These findings indicate that Chinese medicine Gukang prescription can modulate the expression of
core binding factor alpha 1, thereby adjusting the expression of receptor activator of nuclear factor kappa B ligand and osteoprotegerin, which may be one of the mechanisms underlying Gukang treatment for osteoporosis.

To reveal the involvement of oxidative stress in hypertension and insulin resistance. Angiotensin Ⅱ was given to adrenomedullin-knockout mice for 4 weeks. 4-Hydroxy-TEMPOL, a superoxide scavenger mimetic was also employed. The results suggested that adrenomedullin may exert a protective effect against insulin resistance via its intrinsic antioxidant effect.

Based on the subject classification of biomedical engineering in military hospital,the development modes of the discipline are discussed in this paper.

Objective To explore serum levels of visfatin and high-sensitivity C-reactive protein (Hs-CRP) in patients with polycystic ovary syndrome (PCOS), as well as their clinical significance. Methods Ninety patients with PCOS and 30 ovulating healthy women with body mass index (BMI) less than 25 as controls were recruited. PCOS patients were divided to two groups, 48 in obese group with BMI≥ 25 and 42 in non-obese group with BMI<25. Serum level of visfatin was measured by enzyme-linked immunosorbent assay (ELISA) and that of Hs-CRP was assayed by immunoturbidimetry in all participants. Oral glucose tolerance test (OGTT) and insulin sensitivity were assessed in PCOS patients only. Results ①Obese and non-obese patients with PCOS beth presented markedly higher serum levels of visfatin and Hs-CRP than those in controls (t=11.35, 8.46, 10.43 and 8.25, respectively, P<0.05), and levels of visfatin and Hs-CRP were higher in obese group than those in non-obese group (t=7.74 and 6.38, respectively, P< 0.05 ). ②Univariate analysis revealed that serum levels of visfatin and Hs-CRP positively correlated with BMI and homeostasis model assessment insulin resistance, respectively (P<0.05) and serum level of visfatin positively correlated with that of Hs-CRP (P<0.05). Conclusions Chronic inflammation possibly exists in patients with PCOS, which may cause their serum visfatin and Hs-CRP levels increased.

Objective To investigate the effect of CTLA4-Ig chimera protein on mice mortality, histopathological changes, viral fiters, expression of CTLA4 protein on infiltrated T lymphocyte and the balance of Thl/Th2 in mice myocarditis caused by coxsackie virus B3 (CVB3). Methods A total of 106 four to six week-old male BALB/c mice were used in the experiments, which were divided into CTLA4-Ig group (n = 16), CVB3 group (n=40), IgG group (n =40) and normal control group(n = 10) randomly. The mice in CVB3 group, IgG group and CTLA4-Ig group were inoculated intraperitoneally with 0. 15 ml CVB3 and the mice in norreal control group with 0. 15 ml Eagle. The mice in IgG group and CTLA4-1g group were inoculated with IgG (0. I mg/kg) and CTLA4-Ig(0. 1 mg/kg) at 6 h and 72 h post inoculation(p, i. ), respectively, The surplus mice in each group were sacrificed at day 7 p.i. Light microscope was used to quantify the inflammation. The expression of CVB3 mRNA in mycardium were semi-quantified by real-time quantitative polymerase chain reaction (RQ-PCR). The expression of CTLA4 protein were analyzed by immunohistochemistry. The levels of IL-2, IL-4 and 1FN-γ in serum were measured by ELISA. Results The mice mortality, histopathological score and CVB3 mRNA in CTLA4-Ig group were lower than that in CVB3 group ( P < 0.05, P < 0.01, P < 0. 05, respectively). The expression of CTLA4 was significantly increased in CTLA4-Ig therapy group (P < 0.05 ). The serum level of IFN-γ of mice in CVB3 group were significantly higher than that in normal control group( P < 0.01 ). The serum level of IL-4 of mice in CVB3 group were much lower than that in normal control group( P < 0.01 ). The serum level of IL-2 in CVB3 group had no statistical significance with that in normal control group ( P > 0.05 ). The serum level of IFN-γ in mice of CTLA4-Ig group were much lower than that in CVB3 group ( P <0.01 ) and lgG group (P < 0. 01 ). The serum level of IL-4 of mice in CTLA4-Ig group were significantly higher than that in CVB3 group (P<0.01) and IgG group (P<0.01). The serum level of IL-2 in CTLA4-Ig group had no statistical significance with that in CVB 3 control group and lgG group ( P > 0. 0 5 ) . Conclusion CTLA4-Ig may relieve inflammation and reduce mice mortality by blocking the costimulation signals for T lymphocyte activation and reinforcing Th2 response.
