Objective To analyze the correlation of visual acuity and metamorphopsia with foveal morphology before and after vitrectomy with internal limiting membrane peeling (ILMP) in idiopathic macular epiretinal membrane (IMEM) eyes.Methods This is a retrospective case series of 47 IMEM patients (49 eyes).All the patients underwent 25G pars plana vitrectomy with IMEM removal and ILMP.The best corrected visual acuity (BCVA) was measured using the international standard visual acuity chart,and the results were converted to the logarithm of the minimum angle of resolution (logMAR) visual acuity.The severity of metamorphopsia was measured using M-charts.The central macular thickness (CMT),inner nuclear layer thickness (INT),inner retinal layer thickness (IRT),outer retinal layer thickness (ORT),the status of ellipsoid zone (EZ) were assessed with spectral-domain optical coherence tomography at baseline and each month postoperatively.The differences in BCVA,CMT,INT,IRT,ORT and status of EZ before and after surgery were analyzed,so did the correlations between these indexes at the same time.Results Compared with baseline,the postoperative BCVA was significantly increased (F=6.133,P＜0.001),but the M value,CMT,INT,IRT,ORT were significantly decreased (F=12.481,10.565,15.739,6.046,10.569;P＜0.001);the integrity of EZ was improved significantly (x2=12.309,P＜0.001).Preoperative BCVA was positively related to the CMT (r=0.720) and ORT (r=0.720,0.887;P＜0.05),while negatively related to preoperative integrity of EZ (r=-0.295,P＜0.05).The postoperative BCVA was positively related to the preoperative BCVA and postoperative CMT,ORT (r=0.774,0.754,0.842;P＜0.05),while negatively related to postoperative integrity of EZ (r=-0.676,P＜0.05).The preoperative M value was positively related to the preoperative CMT,INT,IRT,and ORT (r=0.931,0.668,0.840,0.637;P＜ 0.05).The postoperative M value was positively related to the preoperative M value and postoperative CMT,INT,IRT,and ORT (r=0.723,0.722,0.767,0.825,0.387;P＜0.05).Conclusions Vitrectomy with ILMP for IMEM can improve the visual acuity,metamorphopsia and foveal morphology.Both visual acuity and metamorphopsia correlate with foveal morphology.

Objective To investigate the immunoregulatory effect of thalidomide on the peripheral blood T-iymphocytes in systemic lupus erythematosus patients in vitro. Methods T-lymphoeytes were treated by thalidomide with different concentrations, then the proliferation of these T-lymphocytes proliferation was deteted by MTT while apoptosis and lymphocyte activation marker were analyzed by flow cytometry. The mRNA expression of IL-6, IL-10 and TNF-α was measured by real-time RT-PCR, One-way ANOVA was used for statistical analysis. Results In vitro, thalidomide inhibited the expression of CD3~+CD28~+ [500 μg/ml group vs the control group, (48±9)% vs (57±9)% P<0.05]. The pro-portion of apoptotic T-lymphoeytes in the 500 μg/ml group was (36±8)%, which was significantly higher than that in the control group [(23±5)%,P<0.05 ]. The values of A_(570nm) T-lymphocytes were significantly lower in the 100 μg/ml group, 300 μg/ml groupand 500 μg/ml group compared with those of the control group ( 100 μg/ml group vs 300 μg/ml group vs 500μg/ml group vs the control group, 0.39±0.05 vs 0.34±0.04 vs 0.30±0.03 vs 0.51±0.07, P<0.05), while thalidomide promoted the expression of CD8~+CD152~+ [ 100 μg/ml group vs 500 μg/ml group vs the control group, (5.0±0.6)% vs (7.8±0.7)% vs (4.2±0.6)%, P<0.05 ]. 500 μg/ml thalidomide inhibited the mRNA expression of IL-6, 2.5～500 μg/ml thalidomide inhibited IL-10, TNF-α mRNA expression of T-lymphocytes.Conclusion Thalidomide can inhibit the proliferative activities and CD28 expression of T-lymphocytes,reduce mRNA expression of IL-6, IL-10, TNF-α, stimulate CD28 expression and apoptosis of T-lymphocytes. These effects may play an important role in it's immune-suppressive effects on systemic lupus erythematosus.

Aim To study the prevalence of blood- lipid level and abnormal lipdemia in Xinjiang pasturing area minority,and select high risk population.Methods A current investigation of 1 084 Mongol and Kazakan people with the methods of random sample, meanwhile, according to criterion to collect vein blood to measure blood TC,TG,LDL- C , to calculate HDL- C with numeration.Statistical analysis with SPSS software package. To take corresponding statistical methods according to characteristics of the documents.Results (1) Hyper LDL- C,low HDL- C are the key types in this pasturing area, the former prevalence was 51.0% and 32.1% among the male and female; and the later was 50.2% and 29.8% (χ 2=39.50,45.60,P< 0.01), both near average standard in our country.(2)Abnormal lipdemia was related to age and sex,that was more higher in the male group than that in female group, and increased with the age, but the female group was more higher than male group over 60 years old.(3)The general standard tendency of HDL- C in female group was higher than that in male group, but with no statistics difference.(4)Compared with other areas,TC,LDL- C standard on the higher level,but TG,HDL- C on the lower.(5)Compared with the blood- lipid level of the same minority ten years before,TC,TG,LDL- C showed an increasing trend,however,HDL- C which had protection to human body showed a decreasing trend.Conclusion The Mongol and Kazakan people in Xinjiang pasturing areas are the hyper prevalence of the abnormal blood- lipid level.The etiology may be connected with the heredity susceptibility, on the other hand,the dietetic structure and habits can not be ignored.

Objective To study the clinical application of the peak expiratory flow rate( PEFR) in children with asthma.Methods The PEFRs of 43 cases of asthma at the acute stage were measured to guide the clinical grading and therapy by the optimum individual PEFR of the patients at the remission stage, and the descending rate and warning value of individual PEFR were determined to investigate the relationship between the individual PEFR descending rate and the asthma attack conditions in the standard and nonstandard monitoring groups.Results At the asthma attack stage, the clinical symptoms became severe with PEFR declining; at the remission stage, the preventive application of drugs was based on the changes of the individual PEEF descending rate . The case number and frequency of asthma attack and the cases subjected to moderate or severe attacks in the standard group were 15 %,23.5 % and 25 % respectively; while those in the nonstandard group were 43.5 %, 75.5 % and 76.9 % respectively, which showed a significant difference( P

Objective To assess the echocardiographic characteristics of embolism and in-hospital mortality in patients with infective endocarditis using three-dimensional transesophageal echocardiography (3D TEE).Methods Retrospective review of 124 patients with native valve infective endocarditis was performed to examine its characteristics by two-dimensional transthoracic echocardiography (2D TTE),multi-plane and 3D TEE.The primary endpoint was embolism and mortality that occurred within one month before or after operation.The combined simple score was calculated by assigning 1 point each for the presence of large vegetation,abscess or fistula,rupture of valvular chord,moderated or severe valvular regurgitation and perforation or serious valvular destruction.Hosmer and area under the curve was calculated to predict embolism and adverse events with the combined simple score,length of vegetation,serious valvular destruction with abnormal morphology.Results In 124 patients,embolic events occured in 27 cases (27/124,21.77％).Multi-plane and 3D TEE can identify the exact location and length of vegetation compared with 2D TTE,which miss-diagnosed vegetation in left atrium and papillary muscle.The clinical presentation of embolism patients was remarkable for lower hemoglobin level (P＜0.05).The ratio of multi-located vegetation,mortality and serious valvular destruction with abnormal morphology were higher in embolism and adverse events patients than those in non-embolism and adverse events patients (all P＜0.05).The area under the curve of combined simple score,lengh of vegetation for embolisms and adverse events and serious valve destruction with abnormal morphology for embolism and adverse events were 0.65 (P=0.06),0.60 (P=0.19)) and 0.70 (P=0.03).Conclusion Multi-plan and 3D TEE plays a key role in the diagnosis of patients with infecitive endocarditis,especially vegetations in occasional location.Serious valve destruction with abnormal morphology is associated with embolism and adverse events.

To obtain the immunized mouse spleen cells, we immnnized the female BALB/C mice I.P. with schizonts or merozoites of the cultured blood forms of Plasmodium falciparum. The immunized spleen cells were fused with the SP2/0 myeloma cells, by which we obtained two strains of hybridoma secreting monoclonal antibodies against human Plasmodium falciparum. Using indirect immunofluorescence assay, we identified that the antibodies reacted only with the surface membrane antigens of the schizonts. These hybridomas were cultured continuously in vitro for over ten months and stably produced antibodies-IgG. The two hybridoma cell lines were designated as AEB2 and AGA4, and the number of their chromosomes was 98 and 100 respectively. The hybridoma cells were injected I. P. into the paraffin oil treated BALB/C mice to obtain the hybridoma ascitic fluid containing monoclonal antibodies. The ascitic fluid inhibited the growth of P. falciparum in vitro up to 89%. The inhibition test showed that antibodies were protective.
