50 mm/h were detected in all the patients. Decreasing C 3 in 6 patients and C 4 in 5 were found. Conclusions SLE is one of the general conditions causing retinal vein occlusion. Visual acuity and barrier of retinal vein and capillary are damaged seriously in patients with retinal vein occlusion caused by SLE, which may be accompanied with other ocular or general lesions. It is suggested that retinal vein occlusion is relative with SLE activity.

Objective To investigate the clinical characteristic of ocular fundus complications in systemic lupus erythematosus (SLE). Methods In 25 cases of SLE with the ocular fundus complications, the ocular fundus, the other ocular tissues, general lesions,and antinuclear antibody (ANA), anti-double-stranded DNA(anti-dsDNA), complement 3 (C 3), complement 4 (C 4)and erythrocyte sedimentation rate(ESR) were analyzed retrospectively. Results In the 25 cases, "classic" SLE retinopathy in 15 (25 eyes), retinal vein occlusion (RVO) in 9 (12 eyes), RVO combined with retinal artery occlusion in 1 (2 eyes), exudative retinal detachment in 1 (2 eyes), vitreous hemorrhage combined with neovascular glaucoma in 1 (1 eye), and optic disc edema except RVO in 3 (6 eyes) were found. Nine cases accompanied with other ocular signs and 21 with general lesions. Positive ANA and anti-dsDNA and elevated ESR in all of the patients, decreasing C 3 in 19, and C 4 in 17 were found. Conclusions SLE can cause serious ocular fundus complications accompanied with other ocular signs. Regular ophthalmic examination should be performed on the patients with SLE to detect and treat the ocular complications promptly.

Objective To establish a new approach for quantitative detection of VAD1 mRNA in cryptococcus neoformans by RT-FQ-PCR, and evaluate the treatment efficacy of CNM. MethodsThe primers and TaqMan probe were designed according to the published sequence of VAD1 mRNA (GenBank),and RT-FQ-PCR method to detect VAD1 mRNA was established. Cerebrospinal fluid from 25 CNM patients and 30 controls were detected and sensitivity and specificity of the method were evaluated. VAD1 mRNA concentration in cerebrospinal fluid from both acute phase and recovery phase of 25 CNM patients were also detected and significance of CNM treatment efficacy with VAD1 mRNA analysis was evaluated. Results Correlation coefficient of standard curve was - 0. 997 9 in detection of VAD1 mRNA by RT-FQ-PCR, and the detection limit was 101 copies/μl. The intra CV of plasmid standard for high, medium and low concentrations were 0. 65% ,0. 89% and 1.23% respectively, the sensitivity of cryptococcus neoformans detection by RT-FQPCR was 96% (24/25) ,while specificity was 100% (30/30). VAD1 mRNA concentration in acute phase were significant higher than that in recovery phase (3. 042 ±0. 906 vs 2. 187 ±0. 665 ,t =4. 583 ,P ＜0. 01).Conclusions The established RT-FQ-PCR method for the detection of VAD1 mRNA is provided with sound sensitivity, specificity and reproducibility, which might be fit for the detection of VAD1 mRNA. The expression level of VAD1 mRNA is relevant with the treatment efficacy of CNM.

Objective To observe the effects of aminoguanidine and Vitamin C on lipid of streptozotocin-induced didbetic rats.Methods Diabetic nephropathy rats were induced by intraperitoneal injection of streptozotocin.Fifty Sprague-Dawley(SD) rats were randomly divided into normal control group,model group,Vitamin C group,aminoguanidine group and Vitamin C associated with aminoguanidine group.All the rats were treated for 16 weeks.During and after the treatment,the general state of the rats was observed and the levels of blood sugar,triglyceride,total cholesterol,low density lipoprotein,high density lipoprotein,glycosylated hemoglobin,and glycated low density lipoprotein in different groups were detected.Results The rats in the four groups suffered diabetes mellitus and renal function lesion.Aminoguanidine and Vitamin C could improve the general state of the rats,but had no effect on the blood sugar.Vitamin C could decrease the levels of triglyceride,serum cholesterol,low density lipoprotein,glycosylated hemoglobin,and glycated low density lipoprotein,and increase the level of high density lipoprotein.There was a synergistic effect with the combination of the two drugs. Conclusion Aminoguanidine and Vitamin C have no effect in the decrease of blood sugar level but have a certain effect on regulating blood lipid.There is a synergistic effect with the combination of the two drugs.

Objective To establish the quantitative detection of capsule associated protein 10 (CAP10)and virulence-associated DEAD-box RNA helicase 1(VAD1)genes in Cryptococcus neoformans (CN) and compare the diagnostic values of single gene test and combined gene test in CN meningitis.MethodsTwenty-three CN meningitis patients with fungal culture or ink staining or CN antigen detection positive in cerebrospinal fluid (CSF) were recruited and patients with craniocerebral trauma were recruited as controls.Standard plasmids were constructed using standard CN strain.Real time fluorescent quantitative polymerase chain reaction (RT-FQ-PCR) was established to detect the mRNA expressions of CAP10 and VAD1 genes in the CSF of patients with CN meningitis,which were compared with the results of CSF ink staining,fungal culture and antigen detection.The diagnostic values of single gene test and combined gene test were compared by chi square test.Results Among 23 CN meningitis patients,22 (95.6％) were CAP10 mRNA positive detected by RT-FQ-PCR,which was significantly higher than both ink staining (16/23,69.6％,x2 =4.167,P＜0.05) and fungal culture (15/23,65.2％,x2=5.143,P＜0.05),respectively; but not significant different from antigen detection (21/23,91.3％,x2=0.500,P＞0.05).There were also no statistical significant differences between combined detection of CAP 10 + VAD1 and CAP 10 or VAD1 single gene test (P＞0.05).ConclusionRT-FQ-PCR detection is successfully established using virulence genes as target,which is superior to the conventional methods.

Purpose:To investigate the relationship between cell apoptosis and dephosphorylated RB protein in human breast cancer. Methods:In our work,human breast cell lines (MCF-7/S,the chemosensitive cell line and MCF-7/ADR,the chemoresistent cell line)were evaluated. Chemosensitivity of two cell lines was evaluated by the MTT colorimetric assay;the expressive levels of dephosphorylated RB protein were detected with immunocytochemistry. Apoptosis rates were determined by flow cytometry(FCM). Results:ADR inhibited proliferation of chemosensitive cell line MCF-7/S ,the 50% inhibition concentration (IC 50 ) was 0.128 ?g/ml;And IC 50 of MCF-7/ADR was 10.89 ?g/ml. The chemotherapeutic sensitivity of MCF-7/S was more than that of MCF-7/ADR by 86 times . Before treatment with ADR,phosphorylated RB protein was positive in two cell lines,but dephosphorylated RB protein was negative;After treatment of different concentration ADR,when the concentration of ADR was increased,expression of dephosphorylated RB protein elevated accordingly in MCF-7/S,but no significant change in MCF-7/ADR. Apoptosis and cell cycle was detected by FCM assays shows ADR induced apoptosis of MCF-7/S more than MCF-7/ADR(P0.05).

Background Attack of primary acute angle-closure glaucoma (PAACG) often cause damage of retinal function.To measure the structural change after acute angle-closure glaucoma attack is of an important clinical significance.Flourier domain OCT(FD-OCT) is available.Objective This study was to measure and compare the thickness of peripapillary and macular retinal nerve fiber layer (RNFL) and macular volume in PAACG patients and normal subjects.Methods A case-controlled study was designed.Twenty-five eyes after acute angle-closure glaucoma attack and 25 fellow eyes were collected from April,2011 to February,2012 in Affiliated Eye Hospital of Wenzhou Medical College,and 25 eyes of normal subjects with the matched age and gender were enrolled at the same period.The thicknesses of RNFL and macula as well as the volumes of macula were measured by FD-OCT in all the eyes 2 weeks after acute angle-closure glaucoma attack.The outcomes were compared among the attacked eyes,fellow eyes and normal control eyes.Results The average thicknesses of RNFL were (125.72 ± 28.57),(108.36 ±9.31) and (106.10± 10.97)μm in the attacked eyes,fellow eyes and normal control eyes,showing a significant increase in the attacked eyes (all at P ＜ 0.05).The RNFL thickness values in the superior,interior and nasal quadrants at optical disc were significantly higher in the attacked eyes than those of the fellow eyes and normal control eyes (all at P＜0.05),but no significant differences were found in temporal and temporal-lower quadrants among the three groups (P=0.081,0.766).The thickness values of macular area were (283.72 ± 18.33),(280.28 ± 16.85) and (289.14±10.60)μm in the attacked eyes,fellow eyes and normal control eyes,with no significant difference among them (Fgroup =2.048,P =0.136),and fellow eyes were significantly reduced in comparison with the normal control group (P＜0.05),and those in the attacked eyes was not significantly reduced in comparison with the normal control group (P =0.224).The macular volumes were (5.589±0.355),(5.532±0.325) and (5.720±0.241)mm3in the attacked eyes,fellow eyes and normal eyes,without statistically significant difference among them (Fgup =1.027,P=0.363).The macular thickness values were lower in the outer race than those of the inner race and followed the pattern of nasal ＞superior＞ inferior＞temporal quadrants.At the temporal,superior,nasal and inferior quadrants of inner race,the temporal quadrant of the outer race,the central area,the macular thickness and volume values were declined in the attacked eyes and fellow eyes compared with the normal control eyes (all at P＜0.05).Conclusions The edema of RNFL is more serious than that of macula in the eyes within 2 weeks after acute angleclosure glaucoma attack.The retinas of macular zone are thinner,and the macular volumes are smaller in the attacked eyes and fellow eyes than those in the normal control eyes.
