AlM: To observe the early tear film changes after trabeculectomy using Keratograph 5M.METHODS:Fourty-one patients (46 eyes) of glaucoma who underwent trabeculectomy were involved. First tear break up time ( FTBUT ) , average tear break up time (ATBUT), non-invasive tear meniscus height (NlTMH), lipid layer thickness and meibomian gland scores were measured at 1d preoperatively and at 1d, 1wk, 1mo postoperatively.RESULTS:At 1d, 1wk and 1mo postoperatively, FTBUT and ATBUT decreased greatly (P<0. 05), as well as lipid layer thickness (P<0. 017). NlTMH at 1d postoperatively increased significantly, but at 1wk and 1mo postoperatively decreased greatly (P<0. 05). There was no significantly difference in meibomian gland scores between preoperation and postoperation (P>0. 05). CONCLUSlON: Keratograph 5M could be used to evaluate tear film function rapidly and accurately. Trabeculectomy significantly alters tear film stability and tear secretion in the short term after operation.

Objective To explore the efficacy of endovascular treatment for closed articular artery injuries.Methods The clinical data of 13 patients from Jan 2010 to Dec 2014 treated for closed articular artery injuries were analyzed retrospectively.The location,severity and extent of arterial injury were confirmed by intraoperative arteriography.The diameter and length of the injured arteries were measured.The guidewire was sent to the lesion site and working wire pathway was established.When the guidewire was difficult to pass through the lesion site,femoral and posterior tibial or radial artery may be used to establish working wire pathway.The stent or stent-graft was implanted through the contralateral femoral artery or distal end of ipsilateral artery.Results Intraoperative angiography confirmed intimal injury (n =2),partial transection (n =5),complete transection (n =5) and arteriovenous fistula (n =1).Eighteen stents or stent-grafts were implanted.Treatment was successful in all patients without peiropeartive death and procedure-related complications.All were followed up for 15 to 48 months and the mean follow-up was (30 ± 11) months.Three patients with stent lumen stenosis less than 50％ as showed by angiography.There was no stent fracture,displacement,or deformation.Conclusions Endovascular treatment for closed articular artery injuries is of less invasion,shorter operative time and quick postoperative recovery.

Objective To explore the neuropsychological development in twin premature infants,and to analyze the risk factors for the retardation of development.Methods The premature infants hospitalized in the Neonatal Ward First Affiliated Hospital of Kunming Medical University from Jun.2010 to Jun.2012 were divided into study groups of twin premature infants and a control group of singleton premature infants.The neuropsychological development of 88 premature infants was evaluated at corrected gestational age of 1 year old by Bayley scales of infant development.According to normal lab findings of the Bayley scales of infant development,the premature infants were then divided into abnormal neuropsychological development group [mental development index(MDI) ≤79 scores] and normal neuropsychological development group (MDI ＞ 79 scores),and the data of 2 groups were statistically analyzed.Results The frequency distribution of MDI score in study group showed a skewed distribution,of which 59％ (27/46 cases) had abnormal neuropsychological development (MDI ≤ 79 scores); However,the frequency distribution of MDI score in control group showed an approximate normal distribution,of which only 12％ (5/42 cases) for abnormal neuropsychological development.Head circumference,body length,body weight,MDI,psycho-motor development index of twin premature infants of one-year old were lower than those of the singleton premature infants of the same age,and the differences were statistically significant (all P ＜0.05).The single factor analysis demonstrated that the risk factors for abnormal neuropsychological development (MDI ≤ 79 scores) of twin premature infants were gestational age,birth weight,mother' s gcstational age,the cultural degree of parents,mode of feeding,neonatal hyperbilirubinemia,neonatal hypoglycemia and neonatal sepsis.Multiple regression analysis showed that neonatal hyperbilirubinemia was the independent risk factor for abnormal neuropsychological development of twin premature infants.Conclusions At same gestational age,neuropsychological development of twin premature infants lagged behind singleton premature infants.Neonatal hyperbilirubinemia may be the risk factors for neuropsychological development of twin premature infants,so the earlier management of neonatal hyperbilirubinemia may be beneficial for the neuropsychological development of twin premature infants.
