Bone xenograft bone for the treatment of bone defect is one of the current research focus, which has advantages of extensive sources, low cost, simple preparation method. While the process of single bone xenograft bone in repairing bone defect is very long, and the clinical outcome is not satisfactory. The main problems focus on formation of bone and vascularization. Reconstituted bone xenograft combined with cells and xenogenic bone material could promote vascularization and bone fusion in vivo, thus achieve a clinical effect of autogenous bone in repairing bone defect.

AlM: To evaluate the function of the microprobe dredging technology in the treatment of meibomian gland dysfunction ( MGD ) and to provide fast, efficient, economical and practical method of treatment for meibomian gland dysfunction ( MGD) .
METHODS:The 100μm diameter stainless steel wire was made as the microprobe with the total length of 3cm, which the needle was about 5mm and hand shank was about 2. 5cm. Selected 140 cases with dry eyes of meibomian gland dysfunction ( MGD ) , patients were divided into two groups and made them have comparability. Observation group ( n = 70 ) used microprobe to dredge meibomian gland pipe accompanied with drugs, hot compress and meibomian gland massage treatment. The control group (n=70) was given conventional drugs, hot compress and meibomian massage treatment. To compare the tear break-up time ( BUT) , efficient rate and the cure rate of the two groups after treatment of 1d, 1wk, 2wk, 1 mo, 2mo and 3mo.
RESULTS: BUT were significantly prolonged in observation group and control group after treatment, and the observation group improved more obviously; the efficient rate and cure rate of the observation group were significantly higher than that of the control group after 1d, 1wk, 2wk, 1mo, 2mo and 3mo treatment.
CONCLUSlON: Using microprobe to unclog the meibomian gland tube can provide the fast and efficient, economical and practical treatment for meibomian gland dysfunction ( MGD ) , which can be promoted in the clinical practice.

Objective To identify the factors of no-reflow during emergency percutaneous coronary intervention (PCI) in patients with acute ST-segment elevation myocardial infarction (STEMI). Methods Atotal of 92 patients with acute STEMI treated with PCI were divided intonormal reflow group(73 patients) and no-reflow group (19 patients) from June 2012 to January 2013. The influencing factors of no-reflow were clarified by comparing clinical symptoms of the two groups. Results The no-reflow rate after undergoing emergency PCI was 20. 7 % in 92 acute STEMI patients. The systolic blood pressure (SBP), type 2 diabetes, troponin T peak, period from disease onset to reperfusion, balloon expansion times and stent number of the target blood vessel were significantly different between the two groups (P<0. 05). Multivariate logistic regression analysis identified that low SBP (SBP<100 mmHg, 1 mmHg=0. 133 kPa), type 2 diabetes, balloon expansion times, troponin T peak, right coronary artery lesions and period from disease onset to reperfusion were the risk factors for noreflow during PCI in patients with STEMI. Conclusion No-reflow following emergency PCI in acute STEMI patients is associatedwith six clinical factors: SBP<100 mmHg, type 2 diabetes, balloon expansion times, troponin T peak, right coronary artery lesions and period from disease onset to reperfusion.

Experiment teaching is a most important item of college teaching, and plays a vital and unexchangeable role to train students for their ability to practice and to innovate. To construct a feasible and scientific examination system of experiment teaching, will significantly help deepen the reformation of experiment teaching and improve the teaching quality. So according to the request for cultivating qualified ap- plication person, we preliminarily constitute the valuation system throughout the whole course and in the final, of theoretic examination and practice examination, and combined with students’ self-valuation and valuation from teachers. In fact, the system works well with a perfect effect.

Objective To investigate the protective effect of basic fibroblast growth factor(bFGF) gene modified mesenchymal stem cells(MSCs-bFGF)on cerebral isehemia in rats.Methods MSCs or MSCs-bFGF were transplanted into rat models of focal cerebral ischemia by intravenous injection.The neurological deficits and infarction volumes were evaluated,and the survival rate and differentiation of grafted MSCs were observed by double immunofiuoreseent labeling.Results In the rat cerebral ischemic model, both MSCs and MSCs-bFGF showed protective effect on the rats in comparison with control group.However, the protective effect was more significant in MSCs-bFGF group.Double immunofluorescent staining showed the number of BrdU-labeled and NeuN co-expression cells in MSCs-bFGF treated animals(127.40?7.43 and 11.20?3.09)were much more than in those of MSCs treated animals.While there was no significant difference between MSCs-bFGF and MSCs group in the number of GFAP co-expression cells.Conclusion MSCs transplantation has protective effect on cerebral ischemia in rats.Basic fibroblast growth factor gene modified MSCs is more effective than MSCs in neuroproteetion.

· AlM: To investigate the correlation of retinal vein occlusion ( RVO ) with blood lipids and carotid artery changes.
· METHODS: Forty cases ( 40 eyes ) with RVO who presented to Eye Hospital of Xinxiang Medical University between May 2013 and April 2014 were selected as the research objects. Proceeded blood lipids and color doppler ultrasonography examination, including total cholesterol ( TC ) , triglycerides ( TG ) , high -density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol ( LDL-C ) , common carotid artery intima-media thickness, carotid plaques, internal carotid artery blood flow mechanics parameters were detected.Thirty eyes ( 30 cases ) were enrolled as control underwent above examinations.
·RESULTS:TC, TG, LDL-C of RVO group was obviously higher than those of the control group ( P<0.05), while HDL-C level was obviously lower than that of the control group ( P<0.05 ). lncidence of carotid artery plaque formation in RVO group was obviously higher than that in the control group. lntima-media thickness ( lMT ) of common carotid artery was obviously increased in RVO group (P<0.05).Both peak systolic velocity ( PSV) and end diastolic velocity ( EDV ) of internal carotid artery reduced (P<0.05), and Resistance index (Rl) increased (P<0.05).The eyes of the sick side and the contralateral carotid artery measured value had no statistical difference ( P >0.05 ) . There were also no statistical difference between ipsilateral and contralateral carotid artery measured value of control group (P>0.05).There were no differences in age, sex between RVO group and control group (P>0.05).
· CONCLUSlON: Lipid metabolism disorder, carotid artery changes is closely related to the pathogenesis of RVO.

Objective: To explore the effect of oxidized low-density lipoprotein (ox-LDL) on Notch 1 expression and cytokine secretion in human acute monocytic leukemia cell line THP1, so as to discuss the role of ox-LDL in atherosclerosis (AS). Methods: THP1 cells were stimulated with PMA to induce human macrophages, which were then exposed to ox-LDL of different concentrations. The morphological changes of the cells was observed by phase contrast microscope. The expression of Notch1 mRNA was examined by real-time quantitative PCR (RT-PCR) and protein expression was measured by Western blotting analysis in the cells. The levels of vascular cell adhesive molecule-1(VCAM-1) and monocyte chemoattractant protein-1 (MCP-1) in supernatants were determined by ELISA. Results: The macrophages differentiated into dendritic like cells 48 h after ox-LDL treatment. Ox-LDL treatment increased Notch1 mRNA and protein expression compared with the control group. Ox-LDL also significantly increased the levels of VCAM-1 and MCP-1 in the supernatant in a dose-dependent manner (P <0.05). The best effect of ox-LDL was seen at the concentration of 50 mg/L. Conclusion: Ox-LDL stimulation can increase Notch 1 expression in THP1 cells; meanwhile, it can also promote the secretion of AS-related cytokines. The role of ox-LDL in AS might be partly mediated by Notch1.
