AIM: To investigate the inhibition of the recombinant human endostatin adenavirus (Ad-Es) on the experimental choroidal neovascularization(CNV) models by intravitreous injection.METHODS: Experimental CNV models were induced by semiconductor laser in 30 male Brown Norway(BN) rats and randomly divided into 3 groups with 10 rats in each group.At 21d after photocoagulation, the single administration group were given intravitreous injection with Ad-Es 0.01mL;the repeated administration group were given intravitreous injection with Ad-Es 0.01mL and a repeated injection 7d later;the saline control group were given intravitreous injection with saline 0.01mL.At 7d after final administration, the leakage of fundus fluorescein angiography (FFA) was observed.Various CNV areas were measured by using laser confocal microscopy of choroidal flatmount method.Pathology and ultrastructure were observed with light microscopy, the expressions of CD105 were measured by immunohistochemistry.RESULTS: The leakage of CNV of the administration group abviously decreased as compared with those in the saline group, the leakage of repeated administration group decreased compared with that of single administration group (P<0.05).Laser confocal microscope quantitative CNV analysis showed that CNV area of the administration group was significantly smaller than that of control group, the area of repeated administration group was smaller than that of single administration group (P<0.05).Under the light microscope, the vascular endothelial cell number and quantity of the administration group were significantly lower than that of the control group, the cell number of repeated administration group was lower than that of single administration group.CD105 expression of the administration group was significantly weaker than that in the saline group;the expression of repeated administration group was weaker than that of single administration group.CONCLUSION: Ad-Es can effectively inhibit semiconductor laser induced CNV in BN rats, and the inhibition effect of repeated administration group is better than that of single administration group.It may be a useful new method in the treatment of CNV.

?AlM:To observe the eye complications in the cases of acute chlorine gas poisoning.
?METHODS:A retrospective review of 121 cases of acute chlorine gas poising with eye irritation, dry eye and other eye complications in Linyi People’s Hospital from February 2009 to February 2013 was performed.
?RESULTS: Among 121 patients, 117 cases ( about 96. 7%) had complications of eye irritation and conjunctival and corneal epithelial damage, and the ocular surface damage was aggravated with the increasing level of chlorine gas poisoning. After 3, 6mo being discharged, 32 and 7 patients respectively occurred dry eye among 115 patients followed up. One mild chlorine poisoning patient, during the hormonotherapy of pulmonary complication, complicated with bullous retinal detachment, of which symptoms and physical signs had been improved after stopping hormonotherapy and adding drugs facilitating fluid absorption. One severe chlorine poisoning patient with loss of consciousness during the treatment, had corneal ulcer and after ulcer being healed with drug and conjunctival flap covering surgery, was left permanent leukoma cornea.
?CONCLUSlON: Acute chlorine poisoning can cause corneal and conjunctival epithelial damage and dry eye. Ocular complications like bullous retinal detachment associated with hormone application should be paid more attention to in the hormonotherapy. For some patients with severe poisoning, the therapy of corneal and conjunctival epitheliums should be taken seriously in case of irreparable damage in rescuing patient’s life.

Objective To explore the correlation between CEUS blood perfusion characteristics and angiogenesis and cell proliferation in nude mice models of gallbladder carcinoma transplant tumor.Methods Nude mice models of gallbladder carcinoma transplant tumor were established.The blood perfusion characteristics of the nude mice models were quantitatively analyzed,CEUS quantitative parameters and the expression levels of microvessel density (MVD),vascular endothelial growth factor (VEGF) and proliferating cell nuclear antigen (PCNA) immunohistochemically were obtained.The correlations were performed.Results Twenty tumors were successfully established.The CEUS of 16 tumors was successful.There was positive correlation between peak intensity (PI) and MVD,PCNA (r=0.635,0.514,P=0.008,0.042).The CEUS parameters were not correlated with expression of VEGF.MVD had positive correlation with expression of VEGF,PCNA (r=0.680,0.650,P=0.004,0.006);VEGF had positive correlation with expression of PCNA (r=0.611,P=0.012).Conclusion The PI of CEUS is positive correlation with MVD and PCNA in nude mice models of gallbladder carcinoma transplant tumor,which may be helpful to evaluate tumor angiogenesis and cell proliferation state.The MVD,VEGF and PCNA positively correlates to each other,which indicates there is the relationship of reciprocal promotion between tumor angiogenesis and cell proliferation,and is good for tumor growth.

Objective To explore the value of combined detection of parathyroid hormone(PTH),β2-microglobulin(β2-MG)and high sensitivity C-reactive protein(hs-CRP)in differentiating diagnosis of acute and chronic renal failure. Meth?ods Patients diagnosed with renal failure was divided into acute renal failure patients group (n=64) and chronic renal fail?ure group (n=74) . Other patients with non-renal failure kidney disease (NRF group, n=80) and healthy adult (control group, n=80) were also selected. Levels of PTH,β2-MG, hs-CRP , PTH+β2-MG, PTH+hs-CRP,β2-MG+hs-CRP and PTH+β2-MG+ hs-CRP were compared between these four groups to choose the optimal combination for differential diagnosis. Re?sults Hs-CRP in ARF group was significantly higher than that in control group and CRF group. Levels of PTH andβ2-MG were significantly lower in ARF group than that in CRF groups but not in control group (P < 0.01). hs-CRP andβ2-MG in the ARF group were moderately higher (68.7%) and severely higher (81.2%) while PTH was mild higher (25%) in ARF group than those in control group, On the other hand, hs-CRP andβ2-MG in the ARF group were moderately higher (56.8%) and severely higher (98.6%) while PTH was mild higher (39.2%) in ARF group than those in control group. Combina?tion of hs-CRP withβ2-MG could increase total case rate (TCR) and Youden index (YI) of ARF;while combination of PTH andβ2-MG could improve the TCR and YI of CRF. Conclusion Combined detection of PTH,β2-MG and hs-CRP is use?ful in differential diagnosis of ARF and CRF.

Objective To provide evidence for effective implementation of influenza and pneumonia immune strategies, we investigated the awareness of influenza and pneumonia and the willingness of vaccination among chronic disease patients.Methods A stratified multistage cluster sampling method was used to investigate 720 patients less than 75 years of age.Results Overall, 717 completed responses were received.The awareness rates of influenza and pneumonia diseases were 59.83% and 59.55%, respectively.However, the awareness rates of influenza and pneumonia vaccine were 17.71% and 6.00%, respectively.The vaccination rate of influenza vaccine was 1.26% while no patients received pneumonia vaccination.Among those not vaccinated the most frequent reasons for not receiving the vaccine included "Believed oneself unlikely to be infected with influenza/pneumonia" and "No recommendation has been received for influenza/pneumonia vaccination".The influence on recommendations by doctors at vaccine clinic and by general practitioner had no significant statistical difference (P>0.05).Conclusion The main reasons for such low awareness and willingness may be due to their poorly knowledge on the risk of influenza/pneumonia diseases, and related vaccines.Health education and intervention should be taken to heighten the vaccination rates of influenza/pneumonia vaccines.

Objective To investigate the effect of hand robot-assisted training based on motor imagery on upper limb function of stroke patients.Methods From November, 2016 to May, 2018, 55 hemiplegic patients with upper limb dysfunction were randomly assigned to control group (n = 25) and experimental group (n = 30). The control group received routine hand motor training, while the experimental group received hand robot-assisted training, for four weeks. They were assessed with simplified Fugl-Meyer Assessment-Upper Extremity (FMA-UE), Wolf Motor Function Test (WMFT) and Modified Barthel Index (MBI) before treatment (t0), one week of treatment (t1), immediately after treatment (t2) and 2 months after treatment (t3).Results The score of WMFT improved in the experimental group at t1 (P ＜ 0.05), with no significant difference between groups (Z =-0.901, P＞ 0.05). The scores of FMA, WMFT and MBI improved in both groups at t2 and t3 (P ＜ 0.05), and the scores of FMA and MBI improved more in the experimental group than in the control group (Z＞-2.073, t＞ 2.034, P ＜ 0.05).Conclusion Hand robot-assisted training based on motor imagery can promote recovery of upper limb function in stroke patients more effective than routine hand function training.

Salvia miltiorrhiza is a highly valued traditional chinese medicine for the treatment of atherosclerosis-related disorders in china, such as cardiovascular and cerebrovascular diseases in China. The wilt disease is serious in the culture of S. miltiorrhiza. Wilt disease cause biomass of plant shoots and roots is lessened, active components are decreased. To solve these problems, we research the pathogen causing wilt disease of S. miltiorrhiza. The suspected pathogen is identified by morphology and etiological test. The identification was further confirmed by alignment the sequences of internal transcribed spacer (ITS) amplified by PCR. Our result show the wilt disease of S. miltiorrhiza mostly occurred in July and August, which is hot and wetter. The wilt disease rate of S. miltiorrhiza continuous cropping for one year in S. miltiorrhiz stubble is 10%, but the wilt disease rate of S. miltiorrhiza continuous cropping for three years in S. miltiorrhiz stubble is 60%-70%. The root rot of S. miltiorrhiz caused by the wilt disease, so the wilt disease was mistaken for the rot root in production. Morphological characteristics show the pathogen is Fusarium oxysporum. The sequence of ITS wes determined and found by BLAST shared 99% identity to that of F. oxysporum f. sp. cucumerinum. So it comes to the conclusion that the causing agent of wilt disease on S. miltiorrhiza belongs to F. oxysporum.

A novel Cu-IUDs material, PU/PEG/Cu nanocomposite, was prepared by melt blending method with thermoplastic polyurethane (PU) as the matrix, with polyethylene glycol (PEG) as a hydrophilic modifier, and with nanometer particles of copper as active matter instead of copper wire or copper tube. The structure, morphology, mechanical properties, thermal stability and water absorption were investigated by using FT-IR, XRD, SEM and so on. The results indicated that the nanometer particles of copper were uniformly dispersed in the matrix in PU/PEG/ Cu nanocomposites. It can be seen that the water absorption ability of this nanocomposite was obviously improved while mechanical properties and thermal stability were at high levels. These results provided a good basis for the studies on the cupric ions release of the nanocomposites in future.
