Objective: To explore independent risk factors of coronary artery calcification (CAC) and analyze correlation among risk factors of CAC and serum osteopontin (OPN) level. Methods: According to results of 64-slice spiral computed tomography (MSCT) coronary angiography, a total of 65 patients were continuously enrolled and divided into CAC group (n=37) and non-CAC control group (n=28). Enzyme linked immunosorbent assay (ELISA) was used to measure serum level of OPN. Single factor and multiple factor Logistic regression analysis’s were used to analyze risk factors of CAC. Spearman’s straight line analysis was used to analyze correlation between risk factors of CAC and serum OPN. Results: 1、 The age, hypertension, diabetes, poor eating habits，lack of exercise, overweight, etc., which were independent risk factors of CAC （OR=3.47～12.96, P=0.018～0.003）by single factor Logistic regression analysis, were inducted to multiple factor Logistic regression analysis, its result showed that age, overweight, poor sleep quality, poor eating habits were independent risk factors of CAC, OR=35.31～5.17, P＜0.01～0.05; 2、Serum level of OPN in CAC group was significant higher than that of non-CAC control group ［(39.919±11.879) μg /L vs. (24.000±6.000) μg /L，P<0.01］; 3、The Spearman straight line correlation analysis indicated that serum level of OPN was correlated with risk factors of CAC : positively correlated with LDL-C, overweight, age, TC（r=0.487～0.286,P＜0.001～＜0.05）, and positively correlated with poor sleep quality, diabetes, poor eating habits, lack of exercise（r=4.10～2.24， P<0.01～0.05）; negatively correlated with HDL-C（r=-0.250,P＜0.05）. Conclusion: Correlation analysis indicates that age, overweight, poor sleep quality, poor eating habits etc. are independent risk factors of CAC；Serum OPN level is correlated with LDL-C, overweight，age, diabetes, lack of exercise etc., so these indicate that must decrease OPN level and risk factors of CAC to relieve CAC and slow down its development.

Objective To observe the expression of survivin and Aurora B in human pancreatic cancer BXPC3 cells after the treatment of sulindac and to explore the potential mechanism. Methods MTr assay was used to determine the effect of sulindac on the proliferation of the BXPC3 cells. RT-PCR was used to detect the expression of mRNA level of survivin and Aurora B, western blot was used to detect protein expression of survivin and Aurora B Thr-232. Cell cycle and apoptosis were detected by flow eytometry (FCM). Results The BXPC3 cells were inhibited by sulindac in a dose and time-dependent manner; the expression of mRNA of survivin and Aurora B were both significantly decreased from 1.5644 and 0.6554 to 0. 4372 and 0.1132 (P< 0.01), the expression of survivin protein and the phosphorylation of Aurora B Thr-232 were also decreased from 1.2735 and 0.4680 to 0.2126 and 0.2546 (P<0.01); the proportion of cells in the G0/G1 phase was increased from (56.65±1.93)% to (70.58±3.21)% (P<0.01). Conclusions Sulindac had inhibitory effects on the growth of BXPC3 cells, the possible mechanism was via decreasing the expression of survivin which depressed the activity of Aurora B, then the CPC was influenced. The most of the cells were blocked in the G0/G1 phase, and the cells' mitosis was inhibited.

Objective To establish a simple and stable model of orthotopic small intestinal transplantation(OIT) in rats.Methods The harvested en bloc segmental intestine consisted of donor abdominal aorta with superior mesenteric artery and portal vein.After in situ infusion with lactated Ringer′s solution,the graft was stored in 4℃ lactated Ringer′s solution.The segmental intestine transplantation was performed by end-to-side anastomosis of donor abdominal aorta to recipient abdominal aorta.The donor portal vein was anastomosed to the recipient left renal vein by "cuff anastomosis".The graft was anastomosed orthotopically by continuous(sutures).Results Sixteen intestine transplantations were,performed the average time for the arterial and(venous) anastomosis was 25?5 min and 4?1 min,respectively.Among the 16 recipient rats,13 survived more than 5 days.The average survival time was 10.35?2.84 days;the longest survival time was 21 days.Conclusions Graft harvesting,the technique of vascular and intestinal anastomosis and the(maintenance) of adequate blood volume are the key points for success of the operation.This successfully(established) model can serve as an excellent animal model for basic research of small intestinal trasplantation.

The study is aimed to understand the resource and the current situation of the use of Cibotii Rhizoma and provide the basis for protecting and utilization. The method of literature survey, field survey and quality assessment were applied in the study. The results showed that all the Cibotii Rhizoma came from wild resource and was mainly founded in Fujian, Guangxi, Guizhou, Yunnan, Guangdong, Hunan, Jiangxi, Sichuan, Chongqing, Zhejiang, etc. It contains over 5 000 000 kg in the area which total is about 7 000 hm2. The annual output is over 850 000 kg. At present, there is no cultivated resources. Based on the investigation and market sampling analysis from various regions, the results showed that the quality of the collected crude drugs conformed with the regulations of the Chinese pharmacopoeia. However the qualification rate of decoction pieces of Cibotii Rhizoma in market was only 56.4%. At present, the resource of Cibotii Rhizoma could meet the needs of medinal uses. It is important to protect the wild resource which is less and less because of the environmental factors. It also need to make a standard of processing method to ensure the safety, and solve quality problem of the decoction pieces.

BACKGROUND: Interleukin-17A has been shown to play an important role in nerve regeneration following corneal injury. OBJECTIVE: To investigate the effect of interleukin-17A on mouse nerve regeneration after optic nerve injury.METHODS: The interleukin-17A-overexpressed adenovirus vector (AV-IL-17A-GFP) was constructed and purified. Adenoviruses with green fluorescent protein (AV-GFP) served as control group. PC12 cell lines were transfected with adenoviruses and the expression efficiency of IL-17A were detected by ELISA. The adenovirus was intravitreally injected into the mouse vitreous body, and the expression level of IL-17A in the optic nerve was determined by immunofluorescence. Afterwards, a mouse model of optic nerve injury was established to observe the nerve regeneration. RESULTS AND CONCLUSION: ELISA results showed that IL-17A was highly expressed in the PC12 cell lines transfected with AV-IL-17A-GFP compared with the control group.Immunofluorescence results revealed that IL-17A was expressed in vivo successfully.There was a significant increase in the number of regenerated axons in the AV-IL-17A-GFP group compared with the control group (P < 0.05). To conclude,AV-IL-17A-GFP can be expressed in the mature neurons in vivo and promote the axon regeneration after optic nerve crush injury in mice.
