AIM: To investigate the effect and safety of laser peripheral iridoplasty combined with iridectomy in the unmanageable acute angle - closure glaucoma by medication.
METHODS:Totally 19 cases (21 eyes) with acute angle-closure glaucoma, including 15 cases ( 17 eyes ) with primary glaucoma and 4 cases (4 eyes) with intumescent cataract - induced glaucoma, were recruited into the study. The intraocular pressure ( IOP ) of all cases were still >21mmHg after 24h drug treatment, and then were treated by laser peripheral iridoplasty combined with iridectomy. The visual accurity, IOP, cornea, peripheral anterior chamber depth, anterior chamber angle and complications were observed at 24h after the surgery.
RESULTS:The mean IOP of all cases was reduced from 53. 09±11. 01mmHg before the surgery to 14. 98±4. 21mmHg at 24h after the treatment, with significant statistical difference ( P< 0. 01 ). The visual acurity of all cases increased in different degrees from handle move to 0. 3 to 0-1-1. 0 at 24h after the treatment. In all cases, cornea edema reduced or cleared up, peripheral anterior chamber depth increased, and anterior chamber angle reopened in different degrees. Complications included iris hemorrhage in 11 eyes (52. 4%), mild iritis in 21 eyes (100%). No cornea burn was encountered.
CONCLUSION: Laser peripheral iridoplasty combined with iridectomy is an effective and safe method for the treatment of the unmanageable acute angle - closure glaucoma by medication.

Exposure to traffic-related air pollutants(TRAP)has been implicated in airway allergic diseases.Recent findings include epidemiologic and mechanistic studies that shed new light on the impact of TRAP on allergic rhinitis(AR)and the biology underlying this impact.These studies have found that oxidative stress induced by TRAP could affect the axis of epithelial cell-dendritic cell-T cell towards a T-helper 2 immune response,which is the major mechanism between TRAP and AR.Further,epigenetics and microRNA might be involved in this process.Our review will summarize the most recent findings in each of these areas.

Objective To investigate the incidence,treatment and prognosis of neonatal respiratory failure (NRF) in the Neonatal Intensive Care Unit of Children's Hospital of Hebei Province.Methods The medical data of 626 NRF newborns admitted to the Neonatal Intensive Care Unit of Children's Hospital of Hebei Province from January 1st,2008 to December 31st,2008 were collected,and the pathogenesis of NRF,management,risk factors of their deaths and cost for the disease were studied.The results were compared with the national study in the same period and the local study of 2004-2005 by Chi-square test.Results During the 12 consecutive months,the incidence of NRF in neonatal intensive care unit was 38.9％ (626/1608).The mortality in hospital was 22.5％ (141/626),among which,most deaths (134,95.0％) occured after early discharge required by the parents.The mortality decreased by 14.7％ compared with that during 2004 2005 (37.2％,113/304),and was also lower than that (24.7％,1683/6864) in the national study at the same period.Pneumonia/sepsis ( 34.8 ％,218/626 ),neonatal respiratory distress syndrome ( 31.6 ％,198/626 ),and meconium aspiration syndrome (10.7％,67/626) were leading primary causes of NRF.The major complications were pneumonia/sepsis (5.4 ％,34/626),intracranial hemorrhage (4.6 ％,29/626) and persistent pulmonary hypertension (3.2％,20/626 ).The percentage of NRF babies requiring pulmonary surfactant rose from 14.1％ (43/304) during 2004-2005 to 23.6％ (149/626) in 2008,which almost reached the national level of 26.8％ (1840/6864).Pulmonary surfactant treatment was accepted by 70.2％ (139/198) patients with neonatal respiratory distress syndrome.12.1％ (24/198)of neonatal respiratory distress syndrome infant was administered immediate intubation-surfactant-extubation.Seventeen (2.7％) patients accepted nitric oxygen treatment.Nasal continuous positive airway pressure was given to 76.5％(479/626) patients,which was higher than before (47.1％,143/304).Conventional mechanical ventilation rate decreased from 72.7％ (221/304) to 49.8％ (312/626),and high frequency oscillatory rate increased from 0.7％ (2/304) to 10.5％ (66/626),which were similar to the national level.Of the 480 patients discharged after recovery,the mean time of hospital stay was (15.1 ± 4.0) days,and the mean medical cost was (12752 ± 5148) CNY.Conclusions The patient number increases and the medical skills and treatment methods of our hospital improve a lot.Utilization of pulmonary surfactant,nasal continuous positive airway pressure and high frequency oscillatory ventilation increase significantly.However,the burden of NRF is still heavy.

Background:Lipopolysaccharide( LPS)and(1,3)-β-D glucan( BG)are involved in the process of Crohn’s disease(CD)by activating immune cells in gut to produce inflammatory cytokines. Aims:To investigate the relationship between LPS,BG and disease activity of CD. Methods:Sixty-eight patients with CD from April 2013 to July 2014 at Shanghai Tenth People’s Hospital were enrolled,of them 41 cases were active-CD( A-CD group)and 27 cases were remission-CD(R-CD group). Twenty healthy subjects were served as normal controls. Crohn’s disease activity index (CDAI)and simple endoscopic score for Crohn’s disease(SES-CD)were used to assess the disease activity and severity. Serum levels of LPS,BG,ESR and CRP were determined,and their relationships were analyzed. Results:Serum levels of LPS and BG in A-CD group were significantly higher than those in R-CD and control groups(P all < 0. 05). No significant differences in serum levels of LPS and BG were found between R-CD and control groups(P all > 0. 05). Levels of LPS and BG were positively correlated with CDAI,SES-CD and ESR(P all < 0. 05),but was not correlated with CRP(P all >0. 05). Conclusions:Serum levels of LPS and BG can be used to assess the disease activity and severity of endoscopic mucosal lesions in CD.
