OBJECTIVETo develop a life quality scale suitable for idiopathic pulmonary fibrosis (IPF) patients, objectively reflecting its changes.

METHODSAuthors first put forward a theoretical structure model of a scale according to patient-reported outcome (PRO) scale formulation principle by combining basic theories of Chinese medicine (CM). Then authors developed an initial scale on the basis of various life quality scales for respiratory disease patients by using structural decision making. Totally 34 patients with confirmed diagnosis of IPF were tested by questionnaire. Items were screened using expert importance scoring method, factor analysis, correlation coefficient method, Cronbach's alpha coefficient method. IPF patient reported outcomes (IPF PRO, IP) were finally defined.

RESULTSA new IP scale was developed covering three areas and 38 items. Pearson correlation coefficient for correlation analysis of clinical symptom scores in ST-George Respiratory Questionnaire and IP scale was 0.828 (P < 0.01). Pearson correlation coefficient for correlation analysis of activity ability scores was 0.929 (P < 0.01). Pearson correlation coefficient for correlation analysis of total scores was 0.862 (P < 0.01). By reliability of IP scale itself (reliability) analysis, Cronbach's alpha coefficient was 0.713. By using factor analysis method for data analysis, KMO statistics was 0.902.

CONCLUSIONIP scale fully reflected the connotation of IPF patients' quality of life, so it could be used as CM clinical therapeutic effect evaluation tool.

Background Cystoid macular edema(CME) is an important cause of visual impairment of central retinal vein occlusion(CRVO).Spectral-Domain optical coherence tomography(SD-OCT) has increased speed and higher resolution,offering a better chance of understanding the morphological changes and pathogenesis of CME. Objective This study was to survey the morphologic features of macular edema associated with CRVO by SD-OCT. Methods Clinical data of the patients with CRVO diagnosed in Department of Ophthalmology,Peking Union Medical College Hospital from March 2008 to August 2009 were retrospectively analyzed.SD-OCT features of macular edema induced by CRVO were analyzed and recorded.Results The average macular foveal thickness was(527.5±218.2) μm in macular edemas eyes.Main morphological changes included 55 cases(84.6%) of CME,15 cases of(23.1%) serous macular detachment(SMD),and 10 cases(15.4%) of simple macular edema,and these findings occurred at the same time in some eyes.Cystoid spaces in the parafoveal region were seen in the inner nuclear layer,outer plexiform layer and outer nuclear layer,and discontinuous or weak inner segment/outer segment(IS/OS) line was often seen in CME.The incidence of CME associated with incomplete posterior vitreous detachment(PVD) was 14.5%,and that of neural epithelial edema associated with incomplete PVD was 10.0%,showing an insignificant difference between them(χ2=0.000,P=1.000).The average area of SMD was 1838.4μm ×1428.1μm×190.1μm,and the incidence of partial PVD was higher(χ2=4.266,P=0.039).Conclusion SD-OCT can reveal the micro-morphological change of macular zone in macular edema eye.SD-OCT enabled visualization of its spatial extent in each retinal layer and the condition of IS/OS layer.Serous macular edema is related with partial PVD.

BackgroundIdiopathic epiretinal membranes(ERMs) is a common eye disease condition that leads to progressive decline of visual acuity. Studying the risk factors relating to this disease will shed light on its pathogenesis and allow opthalmologists to screen the affected individuals among the high-risk population and prepare for prevention and management strategies. ObjectiveThis survey was to investigate the risk factors of idiopathic ERMs in the population undergoing routine health check-ups. MethodsThe clinical data of idiopathic ERMs was obtained from the population of routine health check-ups in Peking Union Medical College Hospital from November 2009 to October 2010. The examination outcomes were compared between the individuals with and without idiopathic ERMs. The demographic and clinical factors associated with idiopathic ERMs were analyzed and assessed using univariate and multivariate logistic regression analyses. Result A total of 27 400 people were included in the survey and idiopathic ERMs were diagnosed in 76 cases. No obvious eye complaint was obtained from the idiopathic ERMs. The number of people affected with idiopathic ERMs was 12 ( 12/11 659 ) in the below 40 years group, 21 (21/4595) in the 51-60 years group and 32 (32/2544) in the over 60 years group. Hypertension, diabetes, diedyslipidemia, renal function insufficiency ,and cataract were found in 42％ ,5％ ,66％ ,6％ and 8％ of the patients, respectively. The univariate logistic regression analyses revealed that significant correlations were found between age,hypertension,hyperlipidemia and history of cataract( P＜0. 01 ). Multivariate regression models showed that the risk of idiopathic ERMs increased in age of 51-60( OR=2. 5,95％ CI:1. 2-5.4,P=0.02) and over 60 years( OR =7.3,95％ CI:3.4-15.6 ,P＜0.01 ) and patients suffering from hyperlipidemia ( OR--2. 1,95％ CI:1. 3-3.5, P＜0. 01 ). ConclusionsOver the age of 50 years and hyperlipidemia are primary risk factors of idiopathic ERM.

Objective Through detecting CD4+CD25+ T regulatory cells(Treg)in the peripheral blood in children suffering autoimmune diseases and normal controls to learn about the changes of Tregs during the diseases and to acquire some references for clinical diagnosis and treatment.Methods The data were reviewed for CD4+CD25+ Treg cells of the 93 children diagnosed as pediatric autoimmune disease in Children′s Hospital Affiliated to Capital Institute of Pediatrics from Nov.2007 to Jun.2008.Thirty-five normal children in the contempora-neous physical examination were selected as the control group.The percentage of CD4+CD25+ Treg cells and CD4+ T cells to the total T cells were determined by flow cytometric method.Data of the JRA group(22 cases),SLE group(12 cases) and HSP group(12 cases),which were the first three according to the number of cases,were respectively compared with the controls.Independent-samples t test was performed for a statistic analysis with SPSS 11.5 software.Results 1.The percentages of CD4+CD25+ Treg cells to the total T cells and CD4+ T cells in the autoimmune diseases children[(6.14?3.21)% and(21.85?11.68)%,respectively] were both higher than those in the control group[(3.68?1.02)% and(12.83?3.61)%,respectively Pa

Background Uveal effusion syndrome is uncommon in clinic.To understand the clinical characteristics of uveal effusion syndrome is helpful for rescuing visual acuity of patient.Objective This study was to discuss the diagnosis,classification and surgical outcome of uveal effusion syndrome.Methods This was a descriptive study.The clinical data of 14 eys from 10 patients with uveal effusion syndrome,ineluding ophthalmologic examination,B-scan sonography,ultrasound biomicroscopy (UBM),fundus fluorescence angiography (FFA),indocyanine green angiography (ICGA),surgical treatment and prognosis,were retrospectively analyzed.The follow-up period was 6 months.Results The fundus findings of all impacted eyes showed bullous-shape retinal detachment (RD).B-scan sonography revealed retinal and choroidal detachment.A annular peripheral ciliochoroidal detachment was observed in the cases under the UBM.FFA exhibited leopard spots without any leakage from choroid into the subretinal space.ICGA demonstrated diffusely choroidal granular hyperfluorescence in the very early phase,which presented with an increasing intensity as time lapse until the late phase.Full-thickness sclerectomy was performed on 4 eyes of 2 patients and subscleral sclerectomy was performed in 1 eye of 1 patient,achieving a retinal anatomic reattachment after surgery.All of the patients finished the fellow-up.No recurrence of RD was seen during the followup duration.Conclusions Comprehensive preoperative evaluation,including ophthalmologic ultrasonography,MRI and CT,is crucial for accurate classification of uveal effusion syndrome and determine of proper management strategy.

BACKGROUND: Vitamin A deficiency disorders (VADD) is a healthy problem of children in the world, especially in the west of China and remote areas, and the nutritional intervention is needed.OBJECTIVE: To compare the improved effects of biscuits fortified with three different doses of vitamin A on the vitamin A status in children aged 3-6 years and explore ap ideal dose of vitamin A supplement for preventing VADD.DESIGN: Randomized controlled observation.SETTING: Health Surveillance Institute, Chongqing Municipal Health Bureau; Staff Room of Nutrition and Food Hygiene, College of Public Health, Chongqing University of Medical Sciences; Center for Children Nutrition, Children's Hospital, Chongqing University of Medical Sciences.PARTICIPANTS: The investigation was done between March and December 2002. 753 children aged 3-6 years from 8 kindergartens in Banan district of Chongqing city were enrolled with the agreement of their guardians. They were divided randomly into 4 groups: 30% recommended intake group, 100% recommended intake group, 20 000 international unit (IU) and 200 000 IU groups.METHODS: ① The biscuits fortified with 30% recommended intake of vitamin A (500 IU) were once given to people of the 30% recommended intake group (177 cases) every day. ②The biscuits fortified with 100% recommended intake of vitamin A (1666 IU) were once given to people of the 100% recommended intake group (173 cases) every day. ③The biscuits fortified with 20 000 IU of vitamin A were once given to people of the 20 000 IU group (209 cases) every week. ④The soft gelatin capsule with 200 000 IU of vitamin A were once given to people of the 200 000 IU group (194 cases).Height, body mass, serum retinal, prealbumin, haematoglobin and retinal binding protein of all children were measured before intervention and after intervention for 3 months. Above indexes were rechecked after supplement for 9 months in 87 children of 30% recommended intake groupMAIN OUTCOME MEASURES: ①Prevalence rate of VADD before in-tervention and after intervention for 3 months in children of every group.② Serum retinal, serum prealbumin, serum retinal binding protein,haematoglobin, height and body mass of children before intervention and after interventional for 3 months in every group.RESULTS: Because of lose of samples and detective technology, only 580 children' examination results were got by rechecking. ①Comparison of the prevalence rate of VADD of children in every group: Three months supplementation later, the prevalence of VADD in every group all decreased sig nificantly [1.48%,1.42%,1.21%, 2.16% ;6.78%,6.54%,8.61%,8.25%(χ2=3.86-8.57, P ＜ 0.05-0.01 )]. ②Comparison of serum retinal, serum prealbumin, serum retinal binding protein, haematoglobin, height and body mass of children of every group: After supplement for 3 months, except prealbumin and haematoglobin in the 30% recommended intake group ,other indexes in each group all increased significantly (t=2.52-37.44, P＜ 0.05-0.01 ). The increase of serum vitamin A in the 20 000 IU group was larger than that in the other groups (F=4.62,P＜ 0.01 ). The increases of haematoglobin, prealbumin and height in the 30% recommended intake group were less than those in the other groups (F=5.04-7.78 ,P ＜ 0.01 ).After supplement for 9 months, the increases of haematoglobin and prealbumin in the 30% recommended intake group were larger than those in the other groups (F= 11.62,10.21 ,P ＜ 0.01). The increase of serum retinal was still lower than that in the 20 000 IU group (F=4.21 ,P ＜ 0.01 ).CONCLUSION: Supplement with biscuits fortified with 3 different doses of vitamin A and capsule with 200 000 IU of vitamin A can improve obviously the nourished status of vitamin A and the level of ferrohemoglobin, in which 30% recommended intake and 100% recommended intake have small risk, and everyday supplement can maintain stably the level of vitamin A. That may be suitable for the long-term supplement for children, and the effect of 30% recommended intake was better than that of 100% recommended intake.

MethodsChronic nephritis in rats was induced by giving adenine 80 mg?kg-1?d-1 orally. Themodel rats were treated by "shen-bing No 5" in different dosages. Levels of urea ni-trogen(BUN), creatinine (Cr), total protein(TP), and Na+ in serum and or urine weredetected and the changes of kidney were obseraed. Results The "shen-bing No 5"markedly lowered the levels of urine protein in 24 hours, BUN in urine and BUN, Na+in serum (P

OBJECTIVETo investigate the prevalence and the risk factors of retinopathy of prematurity (ROP).

METHODSTotally 172 premature infants who were less than 37 weeks postconceptional age, or more than 37 weeks but weighing < 2 500 g at birth, and born at PUMC hospital from May 1, 2003 to November 30, 2004, were enrolled in this study. Their fundus were routinely checked. Diagnosis and staging of ROP were performed according to the international guidelines. Another 20 mature infants were selected as the control group.

RESULTSTwelve infants quitted the treatment or died. The remaining 160 infants completed the follow up. The prevalence of ROP in the premature group was 19.4%, while no ROP was found in the control group. The prevalence of ROP in subgroup with body weight < or = 2 000 g (28.4%) was significantly higher than in subgroup with body weight > 2 000 g (8.3%, chi2 = 10.217, P = 0.001) at birth. The prevalence of ROP in subgroup with postconceptional age < or = 32 weeks (42.5%) was significantly higher than in subgroup with postconceptional age > 32 weeks (11.7%, chi2 = 18.258, P = 0.000). The postconceptional age (OR = 0.959, P = 0.036) and body weight (OR = 0.999, P = 0.026) were the most important risk factors of ROP. Furthermore, blood transfusion ( OR = 0.076, P = 0.029) and Apgar score ( OR = 23.62, P = 0.012) were inversely correlated with ROP. Correlation was not found between ROP prevalence and oxygen inhalation mode, surface active substance, administration of dopamine and dexamethasone, and mother conditions.

CONCLUSIONSThe prevalence of ROP is higher in premature infants than in mature infants. Shorter postconceptional age and lower body weight may result in higher ROP incidence. Routine screening of fundus in premature infants may be helpful for the early detection of ROP.
