Background Endoscopic cydophotoeoagulation (ECP) combined with phacoemulsification (Phaco) and intraocular lens (IOL) (ECP+Phaco+IOL) surgery has been widely used,but its lowing intraocular pressure (IOP) effect is unclear.Objectives This study was to investigate the lowing-IOP effect of ECP+Phaco+ IOL in chronic glaucoma.Methods This experimental process was approved by Experimental Animal Ethics Committee of Medical College of Nanchang University.Chronic glaucoma models were established bilateral eyes of 30 pigmented rabbits using laser 360°trabecular meshwork photocoagulation.Forty-eight model eyes were randomized to four groups.ECP of 180°,270° and 360° was performed in the A,B and C groups,respectively,and Phaco+IOL was simultaneously carried out;while trabeculectomy (Trab) combined with Phaco+IOL surgery (Trab+ Phaco+IOL) was performed in the D group.IOP was measured and compared by iCare rebound tonometer before surgery and 1 day,1 week,2 weeks,1 month,3 months and 6 months after surgery.Results The IOP was(13.31±1.85)mmHg before surgery and that in 1 week after surgery was (33.19±5.59)mmHg,with a significant difference between them (t=94.676,P=0.000).No significant difference was seen among the four groups before operation (P＞0.05).The IOP was significantly lower in the C group compared with the A group and B group in postoperative 1 day (P =0.001,0.035),and in the first week after operation,the IOP was significantly lower in the C group than that of the A group (P=0.013).In the second week after operation,the IOP of the B group was considerably lower than that of the A group,and that of the C group was significant reduced in comparison with the B group (P=0.002,0.006).The IOP was lowest in the C group in postoperative 1 month in comparison with the A,B and C groups (P=0.001,0.009,0.026),and lower IOP was found in the C group compared with the A group in 3 months and 6 months after operation (P=0.008,0.011).In addition,the lowing-IOP range was larger in the group compared with the A group and B group in2 weeks and 1 month after operation (2 weeks:P=0.018,0.014;1 month:P=0.024,0.016).No serious complication was found in various groups.Conclusions Both ECP+Phaco+IOL and Trab+Phaco+IOL can reduce IOP effectively and safely.The lowing-IOP effect is better in larger range of cyclophotocoagulation eye during the ECP+ Phaco+IOL surgery.

Objective To investigate the stress reaction of the medical staff who suffered workplace violence,and provide reference for nursing interventions.Methods 13 medical staff who suffered work-place violence were interviewed through semi-constitutional formula,the data were analyzed by phenomenological method of qualitative research.Results The psychological stress of medical staff mainly included 3 themes:complex emotions,eager to help; psychological adjustment required internal and external integration; different stress reaction affected the psychological state.Conclusions The medical staff suffer seriously from the workplace violence both on the physical and mental health,individuals should learn how to deal with it correctly,and the relevant departments should pay full attention to the humane care to victims of violence,guide them to view the stress correctly,and to take effective measures to prevent and control workplace violence.

BACKGROUNDCarinal resection and reconstruction is an emphasis in surgical treatment of carinal tumor and bronchogenic carcinoma involving carina. The aim of this study is to discuss the clinical value of carinoplasty in lung cancer surgery.

METHODSFrom 1982 to 2004, 41 cases of central bronchogenic carcinoma that invaded the carina accepted carinal resection and reconstruction in this hospital. Of the 41 patients, 25 patients underwent simutaneously additional cardiovascular plasty operation besides carinoplasty. There were 12 different types of carinal resection and reconstruction in this series.

RESULTSThere was 1 perioperative death (because of anastomotic leakage) in this group. Arrhythmia occured in 12 patients, atelectasis in 6 patient and pneumonia in 5 patients. Five patients were assisted ventilation through breathing machine because of pulmonary function failure. The 1-, 3-, and 5-year survival rates were 76.21%, 47.23% and 26.83% respectively.

CONCLUSIONSThe carinoplasty is a good method to treat central bronchogenic carcinoma which invaded the carina. With this method lung cancer tissue can be resected maximally, meanwhile, it can save pulmonary function of patient maximally. Postoperative multi-modality therapy is helpful to increase postoperative survival rate and improve quality of life.

BACKGROUNDTo summarize the surgical treatment for locally advanced lung cancer invading heart and great vessels.

METHODSOne hundred and eighteen cases of lung cancer accepting cardiovascular plasty operation from 1980 to 2001 were reviewed.

RESULTSThe operations included partial resection of left atrium in 38 cases, pulmonary artery resection and restruction in 48 cases, replacement or partial resection of superior vena cava in 25 cases, partial resection of pulmonary conus in 3 cases, and lober replantation in 4 cases respectively. There was no perioperative death, and the 1-, 3-, 5- and 10 year survival rate was 72.68%, 55.20%, 28.62% and 20.36% respectively.

CONCLUSIONSCardiovascular plasty in the surgical treatment of locally advanced lung cancer invading heart or great vessels can remarkably increase the long-term survival and improve the life quality of the patients.
