METHODS: Fifty-eight cases ( 66 eyes ) with cystoid macular edema caused by different diseases were recruited in this study. The included patients were treated with both retrobulbar injection of triamcinolone acetonide and 577nm laser macular grid photocoagulation. The best corrected visual acuity, macular thickness, fundus and intraocular pressure were observed in the 1wk, 1 and 3mo after the treatment in all of the included cases.
RESULTS: After treatment, all of the 66 eyes showed cystoid macular edema partially or completely subsided according to optical coherence tomography and fluorescence fundus angiography; 54 eyes ( 82%) visual acuity improved, 12 vision remained the same.
CONCLUSlON: Retrobulbar injection of triamcinolone acetonide combined with 577nm laser macular grid photocoagulation has good curative effect, simple operation procedure and rare complications in the management of cystoid macular edema.

OBJECTIVETo explore the clinical efficacy of self-made Kirschner wire hook in the treatment of severely displaced proximal humerus fractures in children.

METHODSFrom January 2007 to February 2012,35 children with severely displaced proximal humerus fractures were treated with self-made Kirschner wire hook fixation,including 25 boys and 10 girls with an average age of 13.2 years old ranging from 5 to 17. The duration from injury to operation was 1 to 10 days with an average of 4.5 days. Preoperative diagnoses were confirmed by X-ray films as type III in 26 cases and type IV in 9 according to the Neer-Horwitz classification of the proximal humerus fractures. All fractures were close fracture without nerve or vascular injuries. Anatomical reduction was achieved by open reduction and the fractures were fixed by self-made Kirschner wire hook. Intra-operative and postoperative complications, postoperative radiographic examination, upper extremity length and range of shoulder motion were observed and recorded. Neer score system was used to evaluate shoulder function.

RESULTSAll patients were followed up from 6 to 18 months with an average of 12.1 months. The mean Neer score of the injured side was 94.2 +/- 4.8 (ranged, 84 to 99), 30 patients got an excellent result and 5 good according to the Neer scores. The X-ray showed all the fractures healed without shortening deformity or epiphyseal arrest at early stage. There were no complications related to the implant including loosening or breakage of the self-made Kirschner wire hook. The range of shoulder motion in the injuried side was similar to the normal side, except in abductor lift. All the patients could participate in normal physical activities.

CONCLUSIONThe method of open reduction and fixed with self-made Kirschner wire hook is a safe,effective,convenient treatment for severely displaced proximal humeral fractures in children.

The mycelium growth and sporulation in different temperature, pH value and light conditions were detected by using the crossing and haemocytometer method. The toxicity of five fungicides to Fusarium oxysporum was tested by mycelia growth method, so as to provide the reference for prevention and control against F. oxysporum. The optimum temperature and pH value of F. oxysporum to grow and spore were 28 degrees C and 6-7. Alternating light and darkness promoted growth and sporulation of bacterial colony. As for five fungicides, the EC50 of tebuconazole was 10.02 mg x L(-1), 92.50 times as much as carbendazim. The EC50 of myclobutanil and Fuxing was 91.23, 96.68 mg x L(-1), respectively. Tebuconazole showed the most tremendous inhibitory effect and control efficiency on F. oxysporum.

Objective To summarize the clinical characteristics, diagnosis and surgical management experiences of 51 cases of pulmonary fungal infections. Methods The clinical data of 51pulmonary fungal infection patients hospitalized in department of thoracic surgery of PLA General Hospital from 1981 to 2008 were retrospectively analyzed. Results The recruited cases included three cases of Candida albicans, 22 of Aspergillus, and 26 of Cryptococcus. The clinical symptoms included cough, hemoptysis, fever, chest tightness, chest pain and asthma. Twenty cases were identified through routine healthy examination. Of chest X-ray and computed tomograply scan, 29 cases presented with solid nodules in the lung, some of which had burrs and spikes; 13 presented with pulmonary cavity with even wall thickness and smooth inner wall including 7 with aspergillar glomera.Forty-eight cases underwent standard thoracotomy operations and 3 cases underwent thoracoscope or thoracoscopy-assisted minithoracotomy. Seventeen underwent pulmonary lobectomies, and 34 wedge resections. There was no operative mortality in the 51 patients. All diagnoses were confirmed by postoperative pathology. There was no relapse during 3- 10 years of follow-up. Conclusions Primary pulmonary fungal infections lack characteristic presentations in clinical manifestations and imaging examinations. Pathology is the evidence for definite diagnosis. Surgical intervention is an effective tool for diagnose and treatment of this disease.
