Objective:To explore the clinical correlation of HLA-DRB1 shared epitope with IgA mesangial proliferative glomer-ulonephritis( IgA MsPGN).Methods:The renal function were examined routinely,and HLA-DRB1 shared epitope were determined by PCR in a total of 164 patients with IgA MsPGN and 164 healthy subjects.The renal function and HLA-DRB1 shared epitope were compared in patients with IgA MsPGN and healthy subjects,and clinical correlation of HLA-DRB1 shared epitope and renal function were analyzed.Results:(1)24 h proteinuria,serum creatinine and serum urea nitrogen were significantly different in patients with IgA MsPGN and healthy subjects(P<0.01);(2)The high-frequency gene of HLA-DRB1 in patients with IgA MsPGN were DRB1*04, DRB1*07,DRB1*09,DRB1*11,DRB1*14 and DRB1*15;(3) The distribution frequency of DRB1*09 and DRB1*11 in patients with IgA MsPGN increased significantly(P<0.01 or P<0.05);(4)24 h proteinuria,serum creatinine and serum urea nitrogen in patients with IgA MsPGN with DRB1*09 and DRB1*11 were significantly different compared with those in patients with IgA MsPGN with other HLA-DRB1 shared epitope(P<0.01).Conclusion:HLA-DRB1 shared epitope is related to IgA MsPGN,DRB1*09 and DRB1*11 can increase the risk of IgA MsPGN,and related to the severity of glomerulonephritis.

Objective:To investigate serum level of vascular endothelial growth factor(VEGF)in patients with rheumatoid arthritis(RA).Methods:VEGF ELISA Quantikine kit.The serum RF level was also d etermined using Beckman Array 360.Results:The serum concen tration of VEGF was significantly higher in patients with RA than in healthy co ntrol(P＜0.01).Conclusion:It suggests that VEGF is involved in the pathog enesis of RA and that measurment of serum concentration of VEGF is noninvasive, usful method for monitoring the disease activity of RA.

Objective To investigate the expression and significance of YB -1 in serum and endometrial tis-sues in patients with endometriosis ( EMs ) for taking YB -1 EMs as an index of early diagnosis and treatment . Methods ELISAwas adopted to detect YB -1 expressions in serum of EMs group and control group .The expression of YB-1 in endometrial tissue in the EMs group and control group was detected by immunohistochemistry SP method . Results The average concentration of YB -1 in serum of EMs group (14.65 ±3.91 ug/L) was higherthan thatin the control group (9.64 ±2.37 ug/L), with statistically significant differences (p<0.05).The results of immuno-histochemistry showed that the expression of YB -1 was moderately positive in endometria of patients with EMs . Weakly positive expressions of YB -1 were detected in a fewcases of the control group .There are significant differ-ences in the positive expression rates of YB -1 between two groups ( p <0.05).Conclusion The expression of YB-1 in serum and endometria of patients with EMs is higher .YB-1 can not only be an intracellular marker , but also expected to become an ideal serological marker .

Objective To study the X-ray characteristic of non-bacterial infectious pneumonia in children.Methods In 218 cases of non-bacteria infectious pneumonia, the pathogenic agents included influenza virus,parainfluenza virus,respiratory syncytial virus(RSV),adenovirus,mycoplasma(MYCO) and chlamydia.Of them,mono-pathogenic infection were 152,mixed infection were 66.All the cases had chest conventional radiograph,129 cases were followed up for 2 times or more.The average period of the follow up were 7 days.The findings of chest conventional radiograph were analysed.Results The radiographic features included lung marking heavy 197,disorder 187,straight 105 and obscure 194;pulmonary hilum enlarged 91,hilum obscure 93,emphysema 82,point opacities 81,pulmonary radio-translucent diminution 34,patch opacities 33.In 129 cases followed up the lesions were perfectly absorbed 9(6.97%),partly absorbed 56(43.41%),non-absorbed 53(41.08%),progress 7(5.42%).Conclusion The absorbed period of non-bacteria infectious pneumonia is more 7 days.There are some radiographic characteristcs in RSV and MYCO pneumonia.

Objective: To explore the forecasting method of disease index time series of cucumber downy mildew disease. Methods: Using the time series of cucumber downy mildew disease, we established an autoregressive integrated moving average model, ARIMA (2,2,0) based on model identification, comparison of residual variance, estimation and verification of parameter, observation of the correlation of the estimates matrix, autocorrelation check of the residuals, analysis of the fitting of model and so on. Results: An ARIMA model (2, 2,0) was established: (1+0.487 1B+0.554 7B2) (1-B)2 yt = at, with the Sum of Squared Error (SSE) being 0.001 822 and the Root of Mean Squared Error (RMSE) being 0.008 537. The predicted values of validating date fitted well with the primary values. The established model showed satisfactory forecasting ability and was suitable for forecasting the middle stage and late stage cucumber downy mildew disease. Conclusion: Limiting the alternatives of model by residual variance, together with parameters estimation, the correlation of the estimates matrix, the autocorrelation check of the residuals and the fitting test, can help to search for suitable model quickly and accurately.

Objective To evaluate the effects of branched-chain amino acids-enriched early parenteral and enteral nutrition on the liver function and serum aminograms in cirrhotic rats after partial hepatectomy. Methods In this prospective randomized controlled study, 24 cirrhotic rats, induced by thioacetamide, were randomized into three groups: enteral nutrition (EN) group, EN + branched-chain amino acid (BCAA) group, and parenteral nutrition (PN) + BCAA group. After receiving partial hepatectomy, rats in all three groups were nutritionally supported with equal amount of calorie and nitrogen contents from the 1st postoperative day ( PO day 1 ) to PO day 5. On PO day 6, parameters including body weight, liver functions, prealbumin, transferring, and serum aminograms were measured or determined, and the level of liver albumin mRNA was detected by reversal transcription-polymerase chain reaction and morphological examinations such as HE staining and immunohistochemical staining, which were assessed by index of Ki67 protein index. Results Body weight was significantly decreased in all three groups on PO day 6 (P ＜0.05 ). Compared with EN + BCAA group, serum aspartate aminotransferase, alanine aminotransferase, and alkaline phosphatase after partial hepatectomy were significantly higher in PN + BCAA group (P ＜0.05 ). Serum alkaline phosphatase level was significantly higher in PN + BCAA group than in EN group ( P ＜0. 05). The level of prealbumin was significantly lower in PN + BCAA group when compared with EN group or EN +BCAA group ( both P ＜ 0. 05 ), although no such significant difference was noted in terms of transferrin ( P ＞0. 05 ). The levels of leucine and isoleucine elevated while those of tyrosine, phenylalanine, arginine and tryptophan declined in PN + BCAA group or EN + BCAA group when compared with EN group ( P ＜ 0. 05 ). Aminograms were not significantly different between EN + BCAA group and PN + BCAA group ( P ＞ 0. 05 ). Levels of total amino acid and aromatic amino acid (AAA) were significantly lower while BCAA and ratio between BCAA and AAA (BCAA/AAA) were significantly higher in PN + BCAA group or EN + BCAA group than in EN group (P ＜ 0. 05 ).Significantly lower level of albumin mRNA and index of Ki67 were observed in PN + BCAA group than in EN group or EN + BCAA group (P ＜ 0.05 ) on PO day 6. Conclusions BCAA-enriched EN or PN reverses amino acid disequilibrium and restores BCAA/AAA in cirrhotic rats after partial hepatectomy. Compared with PN, EN is superior in improving postoperative liver function, promoting protein synthesis, and speed up tissue regeneration in the postoperative liver. However, it still can not restore serum albumin in a short term.
