AIM: To explore the predisposing factors, population characteristics and clinical features of severe fungal keratitis.
METHODS:The data of 233 cases 233 eyes of severe fungal keratitis in my hospital from January, 2008 to November, 2013 was retrospectively reviewed. The predisposing factors, population characteristics and clinical features were analyzed.
RESULTS: In 233 cases of severe fungal keratitis, the number of male patients was 153 ( 65. 7%) and the number ratio of male to female was 1. 9:1. The average age of them was (52. 7±11. 3), and most of them were middle-aged and elderly people living in the rural area (78. 1%) and were farmers ( 66. 1%) with low literacy (59. 7%). In 233 cases, 188 cases (80. 7%) possessed a clear history of ocular trauma, mainly caused by plant-based trauma (60. 9%). 90 cases (57. 3%) were infected with Fusarium, and 47 cases ( 29. 9%) by Aspergillus. The main treatment of severe fungal keratitis was surgery (87. 9%). 83 cases ( 52. 9%) were treated with penetrating keratoplasty, and in Fusarium and Aspergillus infected patients with severe fungal keratitis, 58. 4% ( 80/137 ) were performed with penetrating keratoplasty. In addition, patients treated with eye enucleation or evisceration, 68. 4% (13/19) were infected with Fusarium species.
CONCLUSION: Patients with severe fungalkeratitis in our hospital are mainly elderly male farmers living in rural, because of low economic condition and poor diagnosis consciousness. The main pathogens are Fusarium and Aspergillus species, and the major treatment is penetrating keratoplasty. Most of patients with poor clinical outcomes are infected with Fusarium species.

Ten dimeric phthalide racemates (1-10) were isolated from an aqueous extract of the Angelica sinensis root head (Guitou) by separation techniques of column chromatography over macroporous adsorbent resin, MCI resin, silica gel, and Sephadex LH-20, together with preparative thin-layer chromatography and reversed phase HPLC. The racemates were further separated into (+)-/(-)-1-(+)-/(-)-10 with chiral HPLC. Their structures including absolute configurations were elucidated by comprehensive analysis of spectroscopic data, combined with electronic circular dichroism (ECD) and NMR calculations as well as single crystal X-ray diffractions. Compounds (+)-/(-)-1-(+)-/(-)-10 are either new structure or new natural product, named (+)-/(-)-angelidipthalidic acids A-H [(+)-/(-)-1-(+)-/(-)-8] and (+)-/(-)-angelidipthalidols A and B [(+)-/(-)-9 and (+)-/(-)-10], respectively. Meanwhile, dimeric phthalide mono- and bis-lactone derivatives with 3.3′a,8.6′- and 3.6′,8.3′a-coupling patterns as well as determination of their relative configurations are discussed.

Four new triterpenoids, together with six known analogues, were isolated from an aqueous extract of the Ziziphus jujuba var. spinosa seeds, by multiple column chromatographic separation methods using stationary phases of macroporous adsorption resin, MCI resin, normal phase silica gel, Sephadex LH-20, and Toyopearl HW-40C as well as preparative thin-layer chromatography and reversed-phase HPLC. Their structures were determined by spectroscopic data analysis, the new structures were trivially named jujubaceanothoside A (1), 23-epijujuboside A (2), and jujubosides J and K (3 and 4), while the known analogues were identified as jujubosides A-C (5-7) and II (8), alphitolic acid (9), and betulinic acid (10). The structure of 1 was confirmed by single crystal X-ray diffraction.

OBJECTIVETo investigate the result of hip arthroplasty for failed internal fixation of femoral neck fractures.

METHODSFrom June 2007 to January 2014, 29 cases who underwent hip arthroplasty for failed of internal fixation of femoral neck fractures were reviewed. There were 12 males and 17 females. The mean age was 60.3 years (ranged 43 to 83 years) at the time of the fracture. Left hip was in 16 cases, right hip was in 13 cases. The average interval from fracture to arthroplasty was 23.3 months (ranged, 3 to 48 months).

RESULTSAll of 29 cases were performed total hip arthroplasty. There were 20 cases of cementless cup,7 cases of cementless cup with bone graft, 2 cases of cemented cup with bone graft; 13 cases of cementless stem, 16 cases of cemented stem. There were no complications occurred such as intraoperative fracture of the greater trochanter. The average operative time was (115 ± 38) minutes,the mean intraoperative blood loss was (420 ± 175) ml, the average postoperative drainage volume (240 ± 119) ml, intraoperative blood transfusion was (200 ± 220) ml, intraoperative fluid volume was (2,200 ± 400) ml, the average postoperative blood transfusion was (300 ± 200) ml. There was 1 case get postoperative dislocation. All patients were followed up for 14.7 months in average (ranged, 5 to 24 months). There was no revision for mechanical failure. Harris Hip Score significantly was improved from 51.1 ± 7.5 before the conversion to 88.5 ± 6.4 points at the final follow-up.

CONCLUSIONThe effect of the hip replacement for patients with failed internal fixation of femoral neck fractures was confirmed. This method can shorten the time on the bed and reduce the complications. It benefits the patients earlier functional recovery, but it must control operation indication. The long term efficacy is necessary to further observation.

Abstract A method based on dispersive solid phase extraction-high performance liquid chromatography-tandem mass spectrometry for determination of 19 kinds of nonprotein nitrogen compounds including melamine, cyromazine, amidinourea, aminotriazine, 3-aminotriazole, 4-aminotriazole, allantoin, cyanuric acid, dicyandiamide, thiourea, semicarbazide, L-leucine, L-isoleucine, L-arginine, L-hydroxyproline, L-theanine, ammeline, ammelide and guanidine in powdered formulas was presented. The nonprotein nitrogen compounds were degreased by chloroform and extracted by acetonitrile, with MgSO4 to remove water and C18 to clean up. The samples were separated on Merck ZIC HILIC column (150 mm í2. 1 mm, 5 μm, 20 nm) with gradient elution. The electrospray ionization was operated in the positive mode and negative mode, and monitored by the multiple reaction monitoring ( MRM) mode. Allation was quantified by external standard method and the other 18 kinds of nonprotein nitrogen compounds were quantified by internal standard method. All of the correlation coefficients (r) were higher than 0. 99. The limits of quantitation (LOQ) were 0. 05-5. 0 mg/kg, the average recoveries were between 82 . 2% and 115 . 0%, and the relative standard deviations were less than 20%.

Objective To determine the epidemiology of death in PICU in the past ten years.Meth-ods Retrospective cohort study was conducted in the PICU of Childrne ′s Hosip tal of Fud an University from January2005 to December 2014.Resulst The overall mortality rate of PICU was 8.5%overa 10-year peri-od for m January 2005 toD ecember 2014.Compared wti h the period from 2005 to 2009,the mortalti y rate in PICU decreasedf rom 9.7%to 8.0%during ht e period of 2010 to 2014.A totalo f 736 patients died over a 10-year pre iod,including 329(44.7%) infants,191(26.0%) toddlers,118(16.0%) preschoolers,and 98 (13.3%) school-age and adolsec ence.From 2005 to 2009,there were 269 deaths,of which 65.4% were infants and toddlers.From 2010 to 2014,there were 467 deaths,of which 73.7% were infants and toddlers. Among the diseases causing death,the severe pneumonia was the most common disease(21.6%),followed by malignant tumors ( 16.3%) , sepsis ( 15.4%) , accidental injury ( 13.7%) , and severe encephla itis (8.0%).In different age groups,the distribution of the diseases causing death was different,such as infants mainly with sevre e pneum onia(34.3%),t oddlers mainly with accidental injury(16.8%),preschoolers main-ly with accidental injury and malignant tumors(23.7%),school-age and adolescence mainly with malignant tumor(28.6%).From 2005 to 2009,77.5%deaths were critically and very critically ill patients,and the sep sis was the most common cause of death ( 27.6%) especially in very critically ill patients.From 2010 to 2014,83.0%deaths were critically and very critically ill patients,and the accidental injury was the most com-mon cause of death( 23.2%) especially in very critically ill patients, followed by sepsis ( 17.9%).There were 345 deaths ( 46.9%) occurred within the first week of admission, mainly with accidental injury (20.9%).There we re 391 deaths(53.1%) with the PICU stay for 7 or more days,and severe pneumonia (24.3%) was the most common cause of death.Modes of death were categorized as failed cardiopulmonary resuscitation(54.6%) adn forgoing life-sustaining treatme nt(45.4 %).Conclu sion Compared with the pe-riod from 2005 to 2009,the mortality rate in PICU decreaseds gi nificantly during the periodo f 2010 to 2014. The younger the patine t,the higher the mortality rate.Most deaths were attributed to severe pneumonia,fol-lowed by malignant tumors and sepsis.The causes of death also had relations with severity of diseases and lne gth of PICU stay.Failed cardiopulmonary resuscitation and forgoing life-sustaining treatment were still the mostc ommon mode of deaths.
