Alteration in the structural appearance of the optic disk and retinal nerve fiber layer usually precedes the development of reproducible glaucomatous visual field defects.Identification of these changes is important in the diagnosis and treatment of glaucoma at an early to moderate stage and in monitoring its clinical course.This paper reviews the optical coherence tomography(OCT),Heidelberg retina tomography(HRT),optic nerve head stereophotograph(ONHP)and scanning laser polarimetry(SLP) in the field of open angle glaucoma.

0.05).Conclusion There is no association between IL-2 levels in NS and RSV bronchitis.The IL-2 levels show a heterogenous behavior.

Objective To establish the standard values of indicators for care quality evaluation of benign prostatic hyperplasia. Methods To acquire data of nurses configuration in 24 hospitals nationwide by the status survey method. On-spot examination, questionnaire, case-review methods were applied to determine the standard values of 638 benign prostatic hyperplasia patients' care quality in Xi'an three major general hospitals. Department self-report, patients' complaints and quality inspection provided adequate information for determining the standard values. Results The standard values of indicators for care quality evaluation of benign prostatic hyperplasia were successfully established. Conclusions Taking the mean and percentile of indicators as reference can acquire true and reliable results.

Objective To establish the benign prostatic hyperplasia evaluation index system for nursing quality. Methods Indicators framework for perioperative nursing quality evaluation index system was built up by the theoretical research, clinical research, expert meetings approach firstly, then the Delphi method was used to screen and verify the indicators. Results Two rounds of consultation questionnaires were collected with rate of 86.0%, 95.3% respectively, the first round of consultation had the retention of 13 indicators, removed 4 indicators of those. After the second round, the average score of important target was no less than 8.0, and more than half of indicators had a full mark, coefficient of variation targets no higher than 0.20 were up to 100%. Coefficient of concordance of two rounds were 0.241 and 0.433 respectively. ConclusionsAfter two rounds of consultation, there were 13 quality indicators left and experts had well authoritativeness and representative.

Objective：To study the clinical and pathologic features of patients with lupus nephritis (LN) whose myeloperoxidase anti-neutrophil cytoplasmic antibody (MPO-ANCA) were positive. Methods：The clinical and pathological features were analyzed in 18 patients with LN whose MPO-ANCA were positive. And the data of patients with different clinical outcomes were compared. Results：（1）The hematological abnormalities, hypertension and serositis in these patients were more common than general ones with LN. （2）Proteinuria and hematuria were common, the morbidities of gross hematuria and renal failure in these patients were higher than general ones with LN.（3）Various autoantibodies were positive in these patients.（4）Segmental necrosis crescentic nephritis accompanied by density of immunocomplex in glomeruli and vasculitis in intestitium were common.（5）The morbidity of ESRF and mortality of these patients were similar to general ones with LN. The morbidity of tubular atrophy in those with poor prognosis was significantly higher than those survived. Conclusion：The patients with LN whose MPO-ANCA are positive have some difference from those with negative MPO-ANCA, but positive MPO-ANCA is not directly related to the prognosis.

Using the chromosomal DNA of an ice nucleation active bacterium Erwinia ananas 110 as template, an ice nucleation active (ina) gene was amplified by PCR with Taq plusI DNA polymerase. After sequencing and compared with reported ina genes, the cloned gene was identified as a new ina gene and was registered in GenBank at the accession number of AF387802. The new ina gene, named as iceA, has 3921 bp for its coding region, which encodes 1306 amino acids consisting of repetitive segment (R-domain, 1104aa), which is flanked by N-and C-terminal sequences, with 161 aa and 41aa, respectively.

Objective To establish a simple and sensitive method for the determination of serum copper by spectrophotometry.Methods Nitro-PAPS was used as a coloring agent for serum copper in the presence of surfactants Tween-80 and Triton X-100 and the formed complex was measured by spectrophotometry.Results The maximum absorption wavelength of the complex was 570 nm and the molar absorption coefficient was 7.95?10~4 L/(mol?cm).The lineafity of the method was up to 63.0 ?mol/L and the recoveries ranged from 98.6% to 103.1%.The within-run and between-run CVs were 2.1%-3.3% and 2.7%-3.8%.The method(Y)was compared with an AAS method(X)and a correlation of Y=1.01X -0.27(r=0.998 2)was obtained.A reference interval(x~-?2s)determined with this method on 68 individuals was 9.7-24.1 ?moL/L.Conclusions A simple and sensitive method for serum copper has been established.It may used for the analysis of serum copper in clinical laboratories.

Objective:To observe the therapeutic effect of electroacupuncture (EA) at Zusanli (ST 36),Guanyuan (CV 4) and Ashi points on adjuvant arthritis rats,and explore the mechanism of EA treatment of rheumatoid arthritis (RA).Methods:Sixty male rats were randomly divided into a normal group,a model group,a methotrexate group and an EA group,with 15 rats in each group.Rats in the normal group and the model group were routinely raised and did not receive treatment;rats in the methotrexate group received methotrexate at a dose of 0.35 mg/(kg·bw),twice a week for 3 weeks;rats in the EA group received acupuncture at Zusanli (ST 36),Guanyuan (CV 4) and Ashi points,and the bilateral Zusanli (ST 36) and Ashi points were connected to EA apparatus,once a day for 3 weeks.The general status,the swelling degree of the toe,the arthritis index (AI) score,the pathological morphology of the ankle joint,and the mRNA expressions of cellular inhibitor of apoptosis protein (c-IAP) 1 and c-IAP2 in joint synovial tissue cells of the rats in each group were observed.Results:The swelling degree of the toe,AI score and mRNA expressions of c-IAP1 and c-IAP2 in the model group were significantly higher than those in the normal group (all P＜0.05).Compared with the model group,the swelling degree of the toe,AI score and mRNA expressions of c-IAP1 and c-IAP2 in the methotrexate group and the EA group improved (P＜0.01 or P＜0.05);the expressions of c-IAP1 mRNA and c-IAP2 mRNA in rat synovial tissues in the EA group were significantly higher than those in the methotrexate group (P＜0.01).Conclusion:EA alleviates joint swelling in rats with adjuvant arthritis.The mechanism may be related to suppressing mRNA expressions of c-IAP1 and c-IAP2,thus to induce apoptosis of synoviocytes.

This paper analyses the Methods of selecting the cultivation direction of hospital′s dominant disciplines and points out that hospitals should analyse the development environment Objective ly, design the discipline distribution scientifically, and harbor the construction thoughts multi-dimensionally. Based on the practical experience of Nanjing General Hospital, this paper expounds vital Methods to develop preponderant disciplines, proposes that "fusion" and "differentiation" are the developing trend and regards the three major factors-leading talents, strong team, and major projects, as the critical points to prompt the cultivation of preponderant discipline. Lastly, the paper further discusses the implementation of cultivation through strengthening the platform construction, enhancing exchange and cooperation, focusing on achievement transformation and highlighting technical features.

The genus Nodulisporium, is known to produce secondary metabolites with structural diversity. A new alkaloid, 2-hy- droxy-1,1-dimethyl-1,2,3,9-tetrahydro-4H-carbazol-4-one(1), was isolated from the extract of a fungal strain Nodulisporium sp. fermented with rice, together with three known phenols, tyrosol(2), hydroxytyrosol(3), and hydroxytyrosol acetate(4). Their structures were identified by detailed spectroscopic analyses.
