Objective To investigate the levels of peripheral blood plasma M-ficolin/L-ficolin and their correlation with clinical indexes in patients with rheumatoid arthritis (RA).Methods M-ficolin/L-ficolin was detected in the plasma of 61 RA patients who were grouped according to the disease activity and 18 healthy controls by enzyme-linked immunosorbent assay (ELISA).The relationships between the levels of M-ficolin/L-ficolin and laboratory parameters,disease activity were investigated in RA patients.Statistical analysis were performed by t-test,one-way analysis of variance (ANOVA),rank-sum test,correlation analysis was carried out with Pearson/ Spearman rank correlation test.Results ① M-ficolin levels in 61 RA patients were [M (QR) 39 (24) ng/ml] significantly higher than healthy controls (14±4) ng/ml (Z=-5.72,P＜0.05).L-ficolin levels in 61 RA patients were (1.7±0.6) μg/ml obviously higher than healthy controls (1.3±0.5) μg/ml (t=2.55,P=0.013).② The M-ficolin levels of 61 RA patients in low,mediate,high disease activity group were (21±5) ng/ml,[M(QR) 35(13) ng/ml),[M(QR) 50(25) ng/ml].There was significant difference among the three groups (P＜0.01).The L-ficolin levels of 61 RA patients in low、mediate,high disease activity group were (1.2±0.5) μg/ml,(1.7±0.4) μg/ml and (2.2±0.6) μg/ml.There was significant difference among the three groups (P＜0.05).(M-ficolin levels were positively correlated with disease activity score (DAS)28,erythrocyte sedimentation rate (ESR),C reactive protein (CRP),rheumatoid factor (RF),white blood cell (WBC),Note Express User Tool (NEUT),MONO,blood platelet (PLT) (r=0.830,0.692,0.725,0.667,0.388,0.397,0.338,0.476,P＜0.05),L-ficolin levels were positively correlated with DAS28,ESR,CRP,RF,WBC,NEUT,MONO,PLT (r=0.653,0.593,0.630,0.468,0.254,0.302,0.312,0.340,P＜0.05).Conclusion M-ficolin/L-ficolin levels increase in RA patients and correlate with disease activity,which suggests that the complement system may play an important role in the pathogenesis of rheumatoid arthritis.

OBJECTIVE To investigate and analyze the incidence and related factors of nosocomial infection in old inpatients with cancers during radiotherapy and chemotherapy.METHODS Retrospective surveys of nosocomial infection were carried out in 236 old inpatients with cancers from Jan 2005 to Oct 2008.?2 Test was used to evaluate the difference significance of the data.RESULTS The surveys indicated the infection rate was 44.36% and without the sex difference.The infection rate among old inpatients with lung cancer was the highest and counted for 69.39% and then with radiotherapy and chemotherapy that was 56.96%.Respiratory infection was the main infection and counted for 51.27%.The hospital stay time correlated well with the infection rate of the inpatients.With the hospital stay time increasing,the infection rate also increased.Moreover,the predisposing factors of inpatients infection included poor nutrition,advanced stage of tumors,aggressive procedures,leukopenia and application of antibiotics.CONCLUSIONS The nosocomial infection rate of old inpatients with cancers during radiotherapy and chemotherapy is much higher than that of the elders with common diseases and that of the youngers with cancers.The incidence of nosocomial infection is related to the sites of the primary cancers,therapy methods,hospital stay,etc.We must emphasize and control the predisposing factors effectively,and reduce the occurrence of nosocomial infection.

Objective To study the relationship between the T helper cells (Th22)/interleukin (IL)-22 and rheumatoid arthritis (RA) with interstitial lung disease (ILD), and to define the clinical significance of Th22 cells for RA. Methods The quantity of Th22 cells in the peripheral blood from 40 patients with RA (20 RA with ILD, 20 RA without ILD) were examined by flow cytometry, the level of IL-22 in the sera was detected by enzyme-linked immunosorbent assay (ELISA). Comparisons between groups were analyzed by t-test, rank sum test, and the correlation of parameters were tested by linear correlation analysis. Results The quantities of CD4+IL-22+ cells (Th22) in RA patients [(0.15 ±0.07)%] were significantly higher than normal controls [(0.09 ±0.05)%] (t=4.097, P<0.01), and IL-22 levels in RA patients [(83 ±7) ng/L] were significantly higher than normal controls [(61±5) ng/L] (t=13.057, P<0.01). The quantities of Th22 cells in RA-ILD patients [(0.18±0.07)%] were significantly higher than RA-NILD patients [(0.13±0.05)%] (t=2.919, P=0.008), and IL-22 levels in RA-ILD patients [(87±6) ng/L] were significantly higher than RA-NILD patients [(80±6)ng/L] (t=3.624, P=0.001). The quantities of Th22 cells were positively correlated with erythrocyte sedimentation rate (ESR), rheumatoid factor(RF) and 1.4 disease activity score (DAS)28 (r=0.336, 0.377, 0.577, P<0.05),and the level of IL-22 were also positively correlated with ESR and DAS28 (r=0.406, 0.576, P<0.05). Conclusion The quantities of Th22 cells and IL-22 level are increased in RA patients, especially in RA-ILD patients. The quantities of Th22 cells and IL-22 level are positively correlated with ESR and DAS28. It may play a certain role in RA especially in RA with ILD.

Background Toric intraocular lens (Toric IOL) is a well accepted method of correct of corneal astigmatism.Axial misalignment,including the error of intraocular lens alignment during surgery and rotation of Toric IOL,is the main barrier to the precise alignment of Toric intraocular lenses.Therefore,the angle of axial misalignment is a main index to evaluate the effectiveness of Toric IOL implantation.Objective The present study is to describe a method of precisely detecting Toric IOL misalignment using postoperative digital photograph.Methods A measuring template (polar coordinates) was constructed using Adobe Photoshop software.Minimum graduate to detect the Toric axis was 1° (maximum error 0.5°).The clinical data of 24 eyes undergone Toric IOL implantation was retrospectively analyzed.Corneal astigmatism was detected by rotating Scheimpflug camera (Pentacam) or slit scan (Orbscan).Digital retro illumination picture was photographed after mydriasis.The picture was analyzed by our derived template.The steepest corneal axis and the axis of Toric IOL were then determined.The misalignment of Toric IOL was determined as the angle between the steepest corneal axis and the axis of Toric IOL.Misalignment of Toric IOL and its distribution were analyzed by statistical means.Results A method using polar coordinates and digital photo to precisely detect Toric IOL misalignment was derived.Mean Toric IOL misalignment was 10.93±6.90 degrees (0-24 degrees) in the 24 cases.The axial misalignment in all of cases were within 25 degrees,including clockwise in 14 eyes(58.33%),anticlockwise in 10 eyes (41.67%).In this study,the misalignment angle of 4 eyes were within 5 degrees;11 eyes were 5 to 10 degrees;1 eye was 10 to 15 degrees;6 eyes were 15 to 20 degrees;2 eyes were 20 to 25 degrees.Conclusion The method is feasible to the direction of Toric IOL misalignment in clinic.

Objective To compare intraindividual higher-order aberrations(HOA)after implantation of aspherical and spherical intraocular lenses(IOL).Design Prospective,case-controlled study.Participants 33 patients(66 eyes)were between 50 and 76 years of ages.The patients with bilateral senile cataracts were operated with phacoemulsification and IOL implantation.All the patients had no other ocular pathologies and no previous ophthalmic surgery.Patients with keratometric astigmatism higher than-2.0 diopters(D)were excluded from the study.Methods Wavefront aberration measurements of 33 patients(66 eyes)after implantation of a spherical IOL(Canon Staar KS-3)in one eye and an aspherical IOL(Cannon Staar KS-3Ai)in the contralateral eye were analyzed.The eyes were randomly assigned to groups of the spherical IOL or the aspherical IOL.Third-order,4th-order,5th-order,total HOA root-mean-squares(RMS),and 4th-order spherical aberrations(Z40)were compared 3 months after surgery.Main Outcome Measures Visual acuity(VA),the best corrected visual acuity(BCVA),the centrality of IOL,refraction data,diameter of pupil size,3rd-order,4th-order,5th-order and total HOA RMS,and 4th-order spherical aberration(Z40)RMS were measured.Results Fourth-order aberration RMS(0.193?0.098?m),Z40 RMS(0.037?0.099?m),total HOA RMS(0.498?0.072?m)in the aspherical IOL group were lower than those with the spherical IOL(0.403?0.155?m,0.381?0.142?m,0.737?0.164?m,respectively)at 6mm pupil diameter.For 3rd-and 5th-order RMS at 6mm pupil diameter,total HOA RMS(at 5mm pupil diameter),no significant difference was found in both IOLs.Under mesopic conditions,ten patients(30%)with an aspheric IOL had better contrast sensitivity.The average myopic shift were(-0.29?0.09)D and(-0.87?0.16)D in the aspherical and spherical IOL groups at 6mm pupil diameter(P
