AIM: To evaluate the safety and efficacy of intravitreal bevacizumab ( avastin ) injection in patients with exudative age related macular degeneration ( AMD) .
METHODS: The records of patients treated with intravitreal injection of 1. 75mg bevacizumab for AMD were retrospectively reviewed. All patients were evaluated by complete ophthalmic examination, optical coherence tomography and fundus fluorescein and/or indocyanine green angiography. Observation was made on the best corrected visual acuity ( BCVA) , intraocular pressure, and the changes of lens, vitreous, central retinal thickness (CFT) and total macular volume (TMV), at 1d, 3d, 7d, 1mo and 6mo after the treatment and then compared with those of pre - operation. Repeated treatment with intravitreous bevacizumab occurred if there were signs of persistent or recurrent exudation. And all cases were followed up at least 6mo. An intravitreal injection of bevacizumab (1. 75mg) was given once every 6wk.
RESULTS:All 50 eyes of 48 patients with the average of 58±20. 46 years old were included. The mean baseline of BCVA and CFT were 0. 82±0. 53, and 364. 97±151. 83μm respectively. Although there was no significant decrease in mean CFT and TMV one week after the injection, the mean BCVA had significant improvement. At the last visit of 9. 7mo follow - up, BCVA, CRT and TMV showed significant improvements over baseline values. BCVA was improved by at least two lines in 32 eyes (64%),remained stabilization in 18 eyes (36%) at the last visit. A total of 98 injections were performed and the average number of injections was 1. 98 for each eye in the group. About 50%of re - injections gained at least two lines of vision improvement one week postoperatively. There were no serious adverse events during the treatment.
CONCLUSION: Intravitreal bevacizumab ( avastin ) injection for managing CNV due to age-related macular degeneration is safe and few side effects. Intravitreal avastin associated with improvement in visual acuity ( VA ) , which can reduce macular edema and choroidal neovascularization leakage. But a prolonged treatment effect needs further observation.

To evaluate the safety and efficacy of intravitreal bevacizumab injection in patients with macular edema (ME) induced by retinal vein occlusion (RVO).
● METHODS: The records of patients treated with intravitreal injection of 1. 75mg bevacizumab for ME induced by RVO were retrospectively reviewed. All patients were evaluated by complete ophthalmic examination, optical coherence tomography ( OCT) and fundus fluorescein angiography ( FFA ), etc. Best corrected visual acuity (BCVA), intraocular pressure, the change of lens and vitreous, central foveal thickness (CFT) were observed at 1, 2, 3, 6mo after treatment and compared with before treatment. Repeated treatment with intravitreous bevacizumab occurred if there were signs of persistent or recurrent exudation. All the cases were followed up at least 6mo. An intravitreal injection of bevacizumab (1. 75mg) was given at 6wk intervals.
●RESULTS: Fifty patients (56 eyes) with the average of (57±18. 56) years old were included. The mean baseline of BCVA, CFT were (logMAR0. 82±0. 63), (626. 5±178. 0)μm respectively. Although there was no significant decrease in mean CFT at 1wk after injection, the mean BCVA had significant improvement. Followed up at mean 10. 26 ± 5. 87mo, BCVA, CFT showed significant improvements over baseline values. The statistics of CFT at 1, 2, 3mo after injection were significant differences compared with before injection in each of the three groups. CFT at 1, 3, 12mo after injection were (365. 11±23. 212) μ m, (333. 42± 35. 526) μ m, (267. 6 ± 116. 8) μ m, which had a significant difference ( P < 0. 001), namely macular retinal thickness was thinner obviously that before treatment, ME was improved obviously. CFT was no significant difference at each time point after injection in the group of BRVO-ME and CRVO- ME (P> 0. 05). OCT image showed that after injection macular retinal thickness was becoming thinner. FFA showed that after injection macular fluorescein leakage decreased. BCVA was improved by at least two lines in 48 eyes (86%),remained stable in 8 eyes (14%) at the last visit. A total of 112 injections were performed and the average number of injections was 1. 96 in the group. About 50% of reinjections gained at least two lines of vision improvement at 1wk following the retreatment. There was no serious complications during the treatment.
●CONCLUSlON: lntravitreal injection of bevacizumab can improve visual acuity (VA) of RVO (CRVO and BRVO) in patients with ME, relieve ME, reduce the leakage of CNV, and repeated treatment is better. But a prolonged treatment effect needs further observation. There are no serious ocular and systemic complications occurred in our study.

OBJECTIVETo assess the efficacy and safety of balloon dilatation through flexible bronchoscopy in the management of inflammatory stenosis of grade 4-5 bronchus.
METHODThirty patients with inflammatory bronchial stenosis caused by mycoplasmal pneumonia complicated with pulmonary atelectasis were treated with balloon dilatation through fiberoptic bronchoscopy. Before the procedure and after the last operation, therapeutic effect on pulmonary atelectasis were evaluated with CT and all of the patients were followed-up for 1 - 6 months.
RESULTOne to three operations were required to achieve satisfactory dilatation. After balloon dilatation, the average airway diameter increased obviously and the farther airways were opened after the therapy with irrigation. In 25 of 30 cases satisfactory immediate effects were obtained, a narrow airway diameter above expansion significantly increased as compared with preoperative diameter. In 5 children treated with balloon dilatation, the stenosis could not be improved significantly. In 3 patients with hyperplasia of granulation tissue, cryotherapy had to be applied. The operations were ineffective in the other two patients whose course of disease exceeded 3 months. After follow-up periods of 1 - 6 months, chest CT manifestation of expanded sites was improved in 28 patients and atelectasis disappeared. No severe complication was found in any patients.
CONCLUSIONBronchoplasty by balloon dilatation through flexible fiberoptic bronchoscopy is a simple, effective and safe method to treat childhood tracheobronchial stenosis after pulmonary infections.

Objective: To explore the risk predictive value of lipoprotein-associated phospholipase A2 (Lp-PLA2) on acute coronary syndrome(ACS) and to study the relationship between Lp-PLA2 and the severity of coronary stenosis in ACS patients. Methods:A total of 155 ACS patients admitted in our hospital were enrolled. The patient were divided into 2 groups:AMI (acute myocardial infarction) group, n=49 and UA (unstable angina)group, n=106; in addition, there was a Control group, n=44 subjects with normal coronary angiography (CAG).Blood levels of Lp-PLA2 were examined, CAG was conducted and GRACE score, SYNTAX score,Gensini score were calculated. Based on Grace score, ACS patients were divided into 3 subgroups: Low risk subgroup, Grace score≤108, Mid risk subgroup,Grace score 109-140 and High risk subgroup,Grace score≥140.The above parameters were comparedamong different groups. Results: Compared with UA group and Control group, AMI group had increased blood level of Lp-PLA2, P<0.05. Compared with Low risk subgroup, High risk subgroup had much higher Lp-PLA2, P<0.05. Correlation analysis showed that Lp-PLA2 level was positively related to Gracescore (r=0.301, P<0.001). By SYNTAX score and Gensini score evaluation,Lp-PLA2 levels were similar among different subgroups. Conclusion:Blood level of Lp-PLA2 had certain risk predictive value in ACS patients; while it was not related to the severity of coronary stenosis.
