Choroidal neovascularization(CNV)is one of common causes of vision loss.The pathogenesis and development of CNV are a comprehensive process which is regulated by multiple factors and cytokines.Cyclooxygenase-2(COX-2)is an inducible isoform of cyclooxygenase and rate limiting enzyme in the prostaglandin biosynthesis pathway.COX-2 plays an important role in neovascularization by modulating vascular endothelial growth factor(VEGF),migration and apoptosis of endothelial cell.Recently,some experimental studies demonstrated that COX-2 involves in the information of CNV and the inhibitor of COX-2 can suppress CNV.These results provide a new prospect for the prevention and treatment of the CNV.Biological characteristics of COX-2 and its relationship with CNV are reviewed in this article.

Objective To observe the effect of nasal continuous positive airway pressure (nCPAP) and Biphase positive airway pressure (BIPAP) on the oxygen exchange indexes in newborns with mild to moderate neonatal respiratory distress syndrome (NRDS).Methods After infusion of pulmonary suffactant into lung bilaterally,116 cases with mild to moderate NRDS were treated with nCPAP(nCPAP group,n =75) and BIPAP(BIPAP group,n =41) respectively.Oxygen exchange indexes including arterial partial pressure of oxygen [pa (O2)],modified oxygenation index (P/F),alveolar-arterial oxygen tension difference (A-aDO2),respiratory index (RI),artery/alveolar oxygen partial pressure ratio[pa (O2)/pA (O2)] and pulmonary shunt fraction (Qs/Qt) were measured or calculated at 0 (before treatment),2,8 and 24 h after being treated with nCPAP or BIPAP.Results Six different oxygen exchange indexes of Pa (O2),P/F,A-aDO2,RI,pa (O2)/pA(O2) and Qs/Qt in both groups didn't show statistical significance at 0 hour:pa(O2) (kPa) (6.1 ±0.6 vs 6.1 ±0.6,t =0.11,P ＞0.05),P/F(kPa) (15.59 ± 1.45 vs 15.71 ± 1.45,t =1.59,P ＞ 0.05),A-aDO2(kPa)(6.04 ±0.64 vs 6.24 ±0.69,t =1.59,P ＞0.05),RI(6.0 ± 1.0 vs 6.2 ± 1.1,t =1.35,P ＞ 0.05),p,(O2)/pA(O2) (0.24 ±0.02 vs 0.25 ±0.03,t =1.63,P ＞0.05)and Qs/Qt(％)(11.9±1.6 vs 11.6 ± 1.6,t =1.10,P ＞ 0.05).A-aDO2,RI,pa (O2)/pA (O2) and Qs/Qt of BIPAP group had more improvement than those of nCPAP at 2 and 24 h,and oxygen exchange indexes at 2 h of BIPAP group and those of nCPAP group were:A-aDO2 (kPa) (3.83 ±0.49 vs 4.24 ± 0.67,t =18.26,P ＜ 0.05),RI(2.7 ± 0.5 vs 3.3 ±0.7,t =20.59,P ＜ 0.05),p,(O2)/pA(O2) (0.35 ±0.03 vs 0.32 ±0.04,t =15.35,P ＜0.05) and Qs/Qt(％) (8.8 ± 1.6 vs 9.8 ±2.0,t =7.68,P ＜ 0.05) ; 24 h indexes in BIPAP group and the indexes of nCPAP group were:A-aDO2 (kPa) (2.29 ± 1.19 vs 3.07 ± 1.67,t=18.43,P ＜0.05),RI(1.4 ±1.4 vs 2.3 ± 1.6,t=25.02,P ＜0.05),pa(O2)/pA(O2) (0.49 ±0.10 vs 0.42 ±0.11,t =14.96,P ＜0.05) and Qs/Qt(％) (6.5 ±3.0 vs 8.5 ±4.4,t =9.59,P ＜0.05).pa(O2) and P/F of both groups didn't show statistical difference significantly [Pa (O2)(kPa) (12.6 ± 1.0 vs 12.7 ± 1.0,t =3.76,P ＞ 0.05),P/F(28.49 ± 3.17 vs 31.85 ± 2.85,t =3.76.P ＞ 0.05)].Nineteen cases in nCPAP group needed invasive mechanical ventilation,and only 3 cases in BIPAP group underwent the procedure;there was a significant difference (x2 =4.01,P ＜ 0.05).Oxygen exchange indexes in both groups were gradually improved from 2 h,8 h to 24 h,but 22 deteriorated cases showed no improvement,who underwent invasive ventilation.Positive end-expiratory pressure (PEEP) positive airway pressure (EPAP) was (0.42 ± 0.19) kPa in BIPAP group,and (0.56 ± 0.23) kPa in nCPAP group (t =3.45,P ＜ 0.01).Conclusions 1.BIPAP and nCPAP can improve the ability of oxygen exchange in newborns with mild to moderate NRDS,but BIPAP is more effective than nCPAP,which can shorten the possibility of invasive ventilation and reduce the PEEP level.2.p,(O2),P/F,pa (O2)/pA (O2) and RI may be more suitable for evaluating oxygen exchange for neonatal NRDS.

Objective In order to explore the possibility of bone ingrowth into a hollow prosthesis at the bone-implant interface, and the promoting effects induced by rhBMP-2/carrier compound as well. Methods Bone harvest chamber (BHC) modified form Albrektsson designation, was implanted into meta-physis of tibia of New Zealand rabbit to establish an animal model. 10 ?l rhBMP-2 and rhBMP-2/Healon GV compound, each of which contained 1mg rhBMP-2, were loaded into BHC respectively. The same vol-ume of Healon GV and injection water was also loaded into as control. The tissues in the BHC were harvest- ed at 2, 4 and 6 weeks after implantation respectively. Histological observation with non-decalcified slicing technique was adopted, and bone histomorphometry was analyzed by computerized image analysis system to calculate TBV (trabecular bone volume). The data was compared among the different groups. Results At two weeks after loading, there were woven bone formation in groups of rhBMP-2/Healon GV compound and rhBMP-2, and mature bone trabeculae with marrow-like tissue were observed at 4 weeks; At 6 weeks, new bone formation in the BHC became more intensive. However, the tissues in BHC of Healon GV and injection water at 4 weeks were just like those of the former two groups at 2 weeks, and mature bone trabeculae with marrow-like tissue could only been found until 6 weeks. Conclusion Bone at the interface can grow into the contained space of hollow prosthesis through holes at the wall, and form mature bone. rhBMP-2 loaded in the hollow space can obviously promote this effect and the carrier Healon GV has no negative influence but can increase bone inductive effect.

OBJECTIVE:To provide reference for clarifying the pharmacodynamic material basis of anti-inflammation effect of Uygur medicine Hyssopus cuspidatus. METHODS:HPLC was conducted to establish the fingerprint of 8 extracts with different po-larities. Using macrophage RAW264.7 as object,the inhibitory effect of extracts with different polarities on inflammatory factor ni-tric oxide(NO),TNF-α and IL-6 in supernatant of cell culture medium was detected,the differences of anti-inflammatory activity in vitro were compared. Grey correlation analysis method was used to analyze the spectrum-effect relationship of peak area of common peaks and anti-inflammation activity. RESULTS:The fingerprint of 8 extracts with different polarities showed obvious differences. Anti-inflammation in vitro results suggested that 30% ethanol extract had the strongest inhibitory effect on inflammatory cytokines in vitro. There were 14 common peaks in the established HPLC fingerprints,the 5 common peaks that was closely related to the in-hibitory effect of inflammatory factors in vitro were peak 8,6,5,10,13,respectively;peak 8 was rosmarinic acid. CONCLUSIONS:The established fingerprint and its spectrum-effect relationship with anti-inflammation activity in vitro can provide certain reference for its pharmacodynanic material basis study.

Objective To inspect the loading strength of a newly designed femur prosthesis with cage on the tension side for improving its design and clinical application. Methods A straight cementless femur prosthesis of total hip joint with cage on the proximal tension side was designed according to the geometry parameter of proximal femur of Chinese people. The concepts of proximal press-fit fixation, hypo-distal fixation, interface osteointegration and bone fusion with the cage were adopted in the prosthesis. Ti-6Al-4V forging workblanks were used in manufacturing with CAD/CAM technology. One prosthesis was taken randomly from finished products of each No.0, 1, 2, 4 group(with different) matched by (+0, +2) head with 26 mm diameter. The weight-loading test was done at 1 body weigth (BW), 3-8 BW respectively on INSTRON 4507 200kN univeral experiment machine universal material study machine with the prosthesis in a extraversion position of 18?. Results No plastic deformation and crack appeared when any of the prosthesis bear 1, 3-8 BW loading. The ultimate loading limit of No.1 and No.4 prosthesis was 57.6 kN and 81.8 kN respectively. Destroy first appeared at the stress collection area of the neck when the size of neck was relatively small. When the size of neck was big enough, break occurred at the stress collection area of the cage on the tension side. Conclusion The intensity strength of weight-loading of the femur prosthesis can not be destroyed even with a cage on the proximal tension side. It can endure the weight loading of hip in daily activities, and even strengthen due to the bony growing in proximal femur.
