Objective:To compare the difference of serum levels of M-phospholipaseA2 receptor ( PLA2R) antibodies in patients with idiopathic membranous nephropathy(IMN) detected by two different methods and evaluate the diagnostic value of two methods. Methods:Patients diagnosed as membranous nephropathy and other diseases with biopsy-proven from december 2014 to october 2015 in Shengjing Hospital of China Medical University were enrolled and devided into IMN group and non-IMN group. The serum levels of anti-PLA2R antibody were detected by both indirect immunofluorescence assay(IFA) and enzyme linked immunosorbent assay(ELISA). Results:The sensitivity of IFA and ELISA in IMN were 71. 3% and 68. 5%,and the specificities of two methods were the same as 100%. The area under ROC curves of anti-PLA2R antibody for IMN diagnosis were 0. 860 and 0. 839. The diagnostic value of IFA and ELISA was no statistically significant differences in IMN ( P>0. 05 ) , and the consistency of two methods was better (κ=0. 876). The IMN patients of positive anti-PLA2R antibody be susceptible to the low level of serum albumin (P<0. 05). The higher levels of PLA2R antibody were linked with the worse hypoproteinemia and the higher rate of nephrotic-range proteinuria in IMN patients. Conclusion:Two methods of detecting sera PLA2R antibody have higher sensitivity and specificity,so the sera anti-PLA2R antibody was a better biomarker in the diagnosis of idiopathic membranous nephropathy.

Objective To investigate the effects of total flavonoids of litchi chinensis sonn (TFL) on cell proliferation and the molecular mechanism in rat hepatic stellate cells (HSC-T6) activated by growth factor-β1 (TGF-β1). Methods HSC-T6 cells were treated by 0.25%Trypsin-EDTA and then were digested into single cell suspension by DMEM (10%FBS included), which were mixed with TGF-β1 (5μg/L). (1) MTT method was used to detect the proliferation of HSC-T6 cells. Cells were cultured in 96-well plate and were treated by different concentrations of TFL including TGF-β1 group, the control group (5‰DMSO included), and different concentrations of TFL groups (80, 160, 320, 640 and 800 mg/L TFL). Each group has three wells. The absorbance (A) value was measured by enzyme standard meter at the 490 nm wavelength after 24 h, 48 h and 72 h treatment. The cell inhibitory rate was calculated. The subsequent experimental drug concentration and drug treatment time were determined according to half inhibitory concentration (IC50). (2) The expression levels of NF-κB andα-SMA mRNA were detected by PCR (for mRNA) and Western blot assay (for protein). Cells were cultured in the 10 cm culture dish and were divided into different TGF-β1 groups, including TGF-β1 group, the control group (5‰DMSO included), and different concentrations of TFL groups (125, 250 and 500 mg/L TFL). After 48 h, related indicators were measured. Results At the same treatment time point, with the increased concentrations of TFL, A values were gradually decreased, and the cell inhibitory rates were gradually increased. There were no significant differences in the expressions of NF-κB andα-SMA mRNA between TGF-β1 group and control group. And there were no significant differences in the expressions of NF-κB andα-SMA mRNA between TFL125 group, TGF-β1 group and control group. There was a gradually decrease in the expressions of NF-κB andα-SMA mRNA and protein with the increased concentrations of TFL. Conclusion TFL can inhibit TGF-β1-induced HSC-T6 cell proliferation, which is involved in the inhibited expressions of NF-κB andα-SMA to anti-fibrotic effects in liver fibrosis.

Objective To observe the value of ultrasonography, MR and MSCT in diagnosing intravitreous autologous eyelashes. Methods Thirty-two New Zealand rabbits were averagely divided into 4 groups (A, B, C and D) randomly, and 1, 5, 10 eyelashes were implanted into vitreous body of rabbits respectively in group A, B, and C, whereas rabbits in group D (the control group) were only exposed to sham operation without implanting any eyelashes. After one week, all rabbits underwent ultrasound, MR and MSCT examination, then the specimens of vitreous bodies were obtained and observed pathologically. Results All the implanted intravitreous eyelashes were displayed with ultrasound. Intravitreous eyelashes in group A were not detected with MRI, whereas in 3 rabbits of group B and all of group C were displayed on T2WI, T2*WI and SWI sequences. MSCT detected intravitreous eyelashes in only 6 experimental animals. Conclusion Ultrasonography should be considered as the first choice for diagnosis of intravitreous autologous eyelashes. Different sequences of MRI have various advantages in diagnosing intravitreous autologous eyelashes, whereas the diagnostic value of MSCT is limited.
