Background Sustained abnormal tear secretion in dry eye patients may lead to ocular surface and lacrimal glands in the state of long-term inflammatory cell infiltration.Lacrimal gland suffers immune attack by lymphoproliferative,and inflammation interferes normal gland secretion,in which chemokines and their receptors on lymphocytes play a key role.Objective This study was to investigate the inflammation mechanism of delayed allergy induced by Th1 cell in the development of dry eye.Methods Sixty eyes of 30 patients with dry eye and matched 30 healthy volunteers were enrolled in Affiliated First Hospital of Xinjiang Medical University from June to December in 2012.Schirmer Ⅰ test (S Ⅰ t),break up time (BUT) of tear and corneal fluorescence stain (FLS) were performed on the subjects,and conjunctiva epithelial cells were obtained using cytological method of conjunctiva imprinting.Positive cell rates of CC chemokine receptor 5 (CCR5) and CXC chemokine receptor 3 (CXCR3) were detected by flow cytology,and the relative expression levels of regulated upon activation of normal T cells exp ressed and secreted (RANTES),macrophage inflammatory protein (MIP)-lα and MIP-1β,monokine induced by interferon-γ (IFN-γ) (MIG),interferon-γ inducible protein 10 (IP10) and interferon-inducible T-cell α chemoattractant (I-TAC) mRNA were quantitatively assayed by real-time PCR.Differences of the positive rates of CCR5,CXCR3 and lignds were compared between dry eye group and normal control group.Relationship between the positive rates of CCR5,CXCR3 and BUT,S Ⅰ t,FLS scores was analyzed.Results The values of BUT,S Ⅰ t were (2.90±1.37) seconds and (4.00±2.49) mm/5 minutes in the dry eye group,which were significantly lower than (8.56±4.69) seconds and (11.31 ±5.23) mm/5 minutes in the normal control group (t =3.172,2.186,both at P<0.05).FLS scores,positive rates of CCR5 and CXCR3 were0.90±0.57,(3.38±0.66) % and (2.64±0.47)% in the dry eye group,showing significant elevations in comparison with 0.14±0.06,(2.12±0.21) % and (1.12±0.11) % in the normal control group (t=2.297,3.151,5.454,all at P<0.05).In the dry eye group,the masculine rate of CCR5 was negatively correlated with BUT and S Ⅰ t (r=-0.473,-0.385,both at P<0.05).The masculine rate of CXCR3 was negatively correlated with BUT and S Ⅰ t (r =-0.753,-0.684,both at P<0.05).No considerable correlations between the positive rate of CCR5 with the positive rate of CXCR3 or FLS scores (r =0.231,0.336,both at P<0.05).The relative expression levels of RANTES,MIP-1α,MIG and IP10 mRNA in the dry eye group were significantly higher than those in the normal control group (t =3.091,2.894,2.688,2.245,all at P<0.05),but there were no significant differences in the relative expression levels of MIP-1β and I-TAC mRNA between the two groups (t =0.512,1.979,both at P>0.05).The positive correlations were seen between the masculine rate of CCR5 with the relative expression of RANTES or MIP-1α mRNA (r=0.473,0.285,both at P<0.05),but there was no obvious correlation between the masculine rate of CCR5 and the MIP-1 β mRNA expression(r=0.214,P>0.05).In addition,the masculine rate of CXCR3 was positive correlated with the expressions of MIG and IP10 mRNA (r=0.553,0.314,both at P<0.05),whereas the masculine rate of CXCR3 was not related to the expression of I-TAC mRNA (r=0.364,P>0.05).Conclusions Dry eye is probably along with the long-term infiltration of inflammatory cells.The delayed allergy induced by Th1 cells and the nature killed cells is probably the primary cause to xerophthalmia.CCR5,CXCR3 and their ligands might be the regulative targets in the inflammation mechanism of dry eye.

An optimized two-dimensional polyacrylamide gel electrophoresis (2-DE) system for analyzing plant proteins was developed by evaluating different reagents and concentrations used in the sample extraction solutions and lysis buffers. Two main sample preparation methods, referred to as trichloroacetic acid (TCA)-acetone method and phenol extraction-ammonium acetate/methanol (phenol-NH4Ac/methanol) precipitation method, were compared. Four ecotypes of reed plants (Phragmites communis Trin.) from the desert region of north-western China were used as experimental materials: (1) swamp reed (SR) which grows in water about 1 m deep; (2) dune reed (DR) which grows on 5~10 m high sand dunes; (3) heavy salt meadow reed (HSMR) which grows on low-lying salt flats; and (4) light salt meadow reed (LSMR) which grows in the transition area between DR and HSMR growing areas. The optimized phenol-NH4Ac/methanol precipitation method consisted of extracting leaf proteins of different ecotypes of reed with water-saturated phenol and then precipitating with a 5-fold volume of 0.1 mol/L NH4Ac in methanol, followed by dissolving in the lysis buffer. The optimized protein lysis buffer consisted of 7 mol/L urea, 2 mol/L thiourea, 4% CHAPS, 2% Ampholine(pH 3.5~10∶pH 5~8 = 1∶4) and 65 mmol/L DTT. The prepared protein sample (80 ?g) was then separated by 2-DE gel and detected by silver staining method. This improved 2-DE system resulted in a 2-D protein profile of higher resolution and higher protein yields as analyzed by PDQuest software. Good results were also obtained when this 2-DE system was used in 2-D analysis of proteins from other plant materials, such as rice leaves, indicating that it is a suitable 2-DE system for analyzing leaf proteins of different plant species.

BACKGROUND:At present, the separation and culture technique of chondrocytes has been mature, but the chondrocytes grow slowly which are prone to degenerate using the present technique. It is not conducive to the fol ow-up test.
OBJECTIVE:To investigate and improve the separation and culture method of articular chondrocytes of New Zealand rats at 4 weeks of age.
METHODS:New Zealand rats aged 4 weeks were selected to take cartilage tissues from the bilateral knees that were resected under aseptic condition. Chondrocytes were isolated by type Ⅱ col agenase enzyme digestion and mechanical isolation method. The cells were cultured and passaged, and then identified by morphologic observation, toluidine blue staining and type Ⅱ col agen enzyme immunohistochemical methods. Growth curve was pictured by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide method.
RESULTS AND CONCLUSION:Inverted microscope observation showed that the primary cultured chondrocytes adhered at 6 hours after cultivation. The monolayer formation occurred at 72 hours after cultivation, and the cells were ready to be passaged at 96 hours after cultivation. In the fourth generation, some cells represented a spindle-like appearance. In the fifth generation, most cells turned into irregular shape appearance, and cellproliferation capacity diminished. Toluidine blue staining showed that the nuclei of cultured chondrocytes were blue and cytoplasm was pale blue. Immunofluorescent staining showed that cultured chondrocytes had a positive expression of col agen type Ⅱ and the color was tawny. Proliferative rate of chondrocytes in the first to third generations had no differences (P<0.05), while differences were found compared with the fourth generation in 4-7 days (P<0.05) and the fifth generation in 1-7 days (P<0.05). The results indicate that type Ⅱ col agenase enzyme digestion and mechanical isolation method is successful for isolating, cultivating New Zealand rat articular chondrocytes in vitro, and the first to third generations can be the best choice for the experiments of knee osteoarthritis.
