AIM:To establish the murine model of oxygen induced retinopathy ( OIR) and to evaluate the inhibition of retinal neovascularization by erythropoietin ( EPO) blockade.
METHODS: Neonates of C57BL/6 mouse ( P7 ) were exposed to 75%±2% oxygen for 5d and return to normal air environment when 12d ( P12 ) to establish oxygen-induced retinal neovascularization model. The neonates were divided into groups, injected with 0. 5μL solution containing 25ng ( group A), 50ng ( group B), 250ng ( group C) of soluble erythropoietin receptor ( EPO-R) or PBS (group D) at P12, P14 and P16 in the right eye. On P17, the litters were sacrificed and their right eyes were enucleated and fixed with 4% paraformaldehyde, made pathological section. The number of breakthrough internal limiting membrane neovascular nuclei was counted with pathological retinal morphology, understanding theproliferative degree of retinal neovascularization.
RESULTS: The pathological sections showed the neovascular cell nuclei which penetrating the inner limiting membrane in intravitreal EPO receptor injection group was reduced statistically than that in PBS injection group, the difference was statistically significant ( P<0.01). And, neovascular nuclei count differences in the
various concentrations of EPO receptor group was statistically significant (P<0. 01). With the EPO receptor concentration increase, neovascular endothelial cells broken through the internal limiting membrane was reduced.
CONCLUSION: Intravitreal injection of soluble EPO receptor can block EPO and improve neovascularization. The new method is expected to become new treatment of ocular neovascular diseases.

Objective To observe the effect of creatine phosphate sodium on BIS and recovery quality during general anesthesia emergence period in elderly patients.Methods Sixty ASA Ⅰ or Ⅱpatients,31 males,29 females,aged 65-80 yr undergoing transabdominal cholecystectomy by general anesthesia were randomly allocated into two groups(n=30 each):group creatine phosphate (P)and group control(C)according to random numbers generated by computer.Patients were intravenously infused with 1.0 g creatine phosphate sodium melted in 100 ml normal saline or only 100 ml normal saline in group P or C respectively in thirty minutes at the same time of surgical incision.The heart rate(HR)and bispectral index(BIS)were recorded before anesthesia induction (T0 ),during sputum aspiration (T0 ),during extubation (T2 )and 1(T3 ),5(T4 ),10(T5 ),15 minutes (T6 )after extubation. The dosage of propofol,remifentanil and cisatracurium,anesthesia duration,operation time,awake time,extubation time,recovery time of consciousness and Steward recovery scores on T3-T6 were also recorded,and the occurrence of tachycardia during the operation was observed at the same time. Results Compared with T0 ,the BIS value were lower significantly and HR were significantly in-creased on T1-T4 in the two groups(P <0.05).Compared with group C,the BIS value were signifi-cantly higher in group P on T1-T4 (P <0.05).Compared with group C,awake time,extubation time, recovery time of consciousness significantly shortened in group P (P <0.05).There were six cases of tachycardia occurring in group C which were significantly higher than two cases in group P (P <0.05).Steward recovery scores on T3 and T4 were also higher in group P (P <0.05).Conclusion Not only can 1.0 g creatine phosphate sodium administered during transabdominal cholecystectomy im-prove the BIS value of general anesthesia recovery period and recovery quality,but also effectively re-duce the incidence rate of tachycardia during operation in elderly patients.

Objective To investigate the role of RNA-binding protein La protein in the invasion and migration of cervical cancer cells.Methods RNAi technology was used to silence the La protein in HeLa cell,a cell line of cervical cancer,and then screened by G418.Finally the stably expressed HeLa-shLa cell line was constructed and then wound healing,Transwell,Western blot and gelatin zymography assay were performed. Results After La protein HeLa was silenced by RNAi,the invasion and migration capabilities of HeLa cells were decreased significantly compared with those of the controls.Meanwhile,SiRNA-mediated depletion of La reduced the expression of MMP-2 and increased the expression of TIMP-2.Meanwhile the activity of MMP-2 was reduced too.Conclusion RNA-binding protein La promotes the invasion and migration of cervical cancer cells,which may be related to regulating its matrix metalloproteinases and inhibitors.

This study is to establish the methods for determination of iridoid glycosides and triterpenic acids in Corni Fructus and provide technical support for the quality control of Corni Fructus. Morroniside, loganin and sweroside were determined by HPLC-UV method with acetonitrile and 0.1% formic acid as the mobile phase, and the detective wavelength was set at 240 nm. Oleanolic acid and ursolic acid were determined by HPLC-ELSD method with methanol-0.5% ammonium acetate (87:13) as the mobile phase. The results showed that the linear ranges of morroniside, loganin and sweroside were 5.335-213.4 mg · L(-1) (r = 0.9999), 5.515-220.6 mg · L(-1) (r = 1.0000), 1.992-79.68 mg · L(-1) (r = 1.0000), respectively. The average recoveries of the above three iridoid glycosides were 98.49%-99.28% with RSDs of recoveries being less than 2%. The linear ranges of oleanolic acid and ursolic acid were 7.74-154.8 mg · L(-1) (r = 0.9964), 10.82-216.4 mg · L(-1) (r = 0.9996), respectively. The average recoveries of the above two triterpenic acids were 98.11%-99.27% with RSDs of recoveries being less than 3%. The method established in this research is simple, rapid and reliable, and can be used for quality control of Corni Fructus. Furthermore, the research provided experimental data for the improvement of present quality standard of Corni Fructus, which has important significance to guarantee its quality and clinical curative effect.

Acupuncture has remarkable effects of pain relieving and functional restoration on injuries of soft tissue and joint due to military training. As more and more attention has been attached to the impact of psychological states and biorhythm disorder on the fighting ability of military staff, acupuncture has found its place in treating chronic fatigue, combat stress reaction, traumatic brain injury and post-traumatic stress disorder as well as regulating circadian rhythms. The therapeutic effect of acupuncture in military training-related physical damage and psychological trauma has already been proved by numerous clinical practices and researches. It is held that using acupuncture as an alternative could not only save medical resources, but also enhance the fighting ability of the army. However, the current clinical studies is facing the problem of limited sample size. Therefore, randomized controlled trials in large scale and multiple centers should be further carried out toward military staff, so as to provide more speaking evidences to the prevention and treatment of physical and psychological diseases.

HPLC analysis was performed to study the changes in chemical composition of ginseng extracts prepared from high quality ginseng with 0, 2, 4, 8 h of steamed times. An UFLC-MS/MS multiple-reaction monitoring (MRM) quantitative analysis was made to investigate the pharmacokinetic behavior differences of ginsenosides in mice ig administered of ginseng extracts with different steamed times in the negative ion mode, with Digoxin as the internal standard substance. The mice were injected with LPS to establish inflammation model after ig administration of ginseng for a week and the contents of tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) in mice plasma were detected by ELISA, in order to study on anti-inflammatory effects of ginseng with different steamed times. It was determined that levels of TNF-α and IL-1β were significantly decreased in inflammation model group ig administered of ginseng extracts with 8h of steamed time. The results showed that the chemical components in ginseng changed after steaming and the components into the blood changed, correspondingly. Ginseng with steamed 8 h contributes to anti-inflammatory effects. These results provided an experimental basis for revealing the active substance basis and dose-effect relationship of ginseng on anti-inflammatory effect.

Objective To assess left ventricular (LV) global systolic function in patients with essential hypertension with normal geometric LV by 3-dimensional ultrasound speckle tracking imaging(3D-STI). Methods Fifty patients with essential hypertension were enrolled in this study, 29 normal subjects matched with age and sex were selected as control groups. LV global longitudinal peak systolic strain (GLS), radial peak systolic strain (GRS), circumferential peak systolic strain (GCS), LV global 3-dimentional radial peak systolic strain (3DGRS) were measured in all subjects by 3D-STI from the apical full-volume image and compared between groups. LV ejection fraction (LVEF) was acquired from 3D-STI.Results Compared with controls, LV GLS, GRS, GCS and 3DGRS were significantly reduced in patients with hypertension ( P ＜ 0.05 for all). A Pearson correlate revealed that LV GCS, GLS and GRS corresponded with LVEF( r1 =0.930, P1 ＜0.001; r2 = 0.705, P2 ＜0.001; r3 =0.474, P3 =0.001,respectively) in patients with hypertension, and LV GCS, GLS correlated with LVEF( r1 = 0. 838, P1 ＜0. 001; r2 = 0. 697, P2 ＜ 0. 001, respectively) in normal subjects. Conclusions LV global 3D strain decreases in patients with hypertension in the early period,3D-STI could evaluate the early change of heart function in patients with hypertension. LV circumferential movement plays a major role in the LV 3D movement and impacts on LVEF.

Objective To assess the effectiveness and safety of Azithromycin for preventing bronchopulmonary dysplasia(BPD) in preterm infants in order to provide reference for the clinical treatment of BPD.Methods The electronic retrieval were conducted to review randomized controlled trials (RCTs) from The Cochrane Library,PubMed,EM-Base,China Biological Medicine Database (CBM),Chinese Journals full-text Database (CNKI),Chinese Technological Journals Database(VIP) and Wan Fang Digital Journal Full-text Database by free texts and medical subject headings.The retrieval time was from inception to Dec.2012.Randomized or quasi-randomized studies were conducted by comparing Azithromycin therapy and no treatment or placebo management to prevent BPD among the preterm or low birth weight infants were included.The reference lists of relevant trials and conference proceedings were searched.Risk biases of the trials were assessed.Statistical analysis was performed by using Revman 5.1 offered by Cochrane.Results A total of 2 trials including 328 preterm infants were included.No significant difference was observed between the Azithromycin group and the control group in the incidence of BPD(RR =0.81,95％ CI 0.55-1.19).The risk ratio of death and post-natal steroid used in the Azithromycin group were lower,but there was no difference.The risk ratio of length of stay was not significantly different.The rate of BPD in preterm infants who had a positive respiratory culture of Ureaplasma between the preventative Azithromycin group and the placebo group showed that the incidence of BPD was significantly less in the Azithromycin group.Conclusions The available data are insufficient to make a recommendation regarding treatment with prophylactic Azithromycin to prevent BPD in preterm infants.More RCTs with large-scale and high-quality are required to provide more reliable evidence.
