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.

Background Triamcinolone acetonide (TA) is often used in the treatment of uveitis and fundus disease,but whether it has toxic effect to normal tissue around eyes is unclear.Objective The aim of this study was to explore the adverse and toxic effects of TA on the periorbitally normal tissue following the periocular injection.Methods Twenty-seven New Zealand albino rabbits were randomly divided into experimental group,normal saline solution group and blank control group.TA was periocularly injected twice (20 mg for each) at 1-month interval in the rabbits of the experimental group,and 0.5 ml normal saline solution was used in the same way in the rabbits of the normal saline solution group.Not any drug was used in the blank group.The rabbits were sacrificed 1 month and 2 months,3 months after the secondary injection.For the preparation of the specimens of extraocular muscles,peribulbus adipose tissue,lacrimal gland and optic nerve.Hematoxylin and eosin staining of the specimens was performed to examine the the pathological change under the optical microscope,and the ultrastructural of peribulbus tissues was observed under the transmission electron microscope.Results No statistically significant change was found in IOP among various time points and groups (Fgroup =0.952,P =0.881 ; Ftime =7.297,P =0.411).The hyphological structures and ultrastructure of extraocular muscles,peribulbus adipose tissue,lacrimal gland and optic nerve were normal in the rabbits of the normal saline solution group and the blank control group.However,the optical microscopy showed varying degrees of atrophy or dissolving in the extraocular muscle fibers,the increase of glandular epithelial cells and enlargement of nuclei in the lacrimal gland as well as visible disorder arrangement of nerve fibers,vacuoles degeneration and the decrease of glial cells in optial nerve tissue in the rabbits of the experimental group from 1 month though 3 months after the secondary injection.Under the transmission electron microscope,the muscle stripes,bright band and dark band were incompletely disappeared,and expansionary sarcoplasmic reticulum and oval nucleus at the inferior to sarolemma were seen in the extraocular muscles.In addition,swelling lacrimal gland epithelial cells,thickening nuclear membrane and more organelles were exhibited in the lacrimal gland.In the optic never tissue,uneven myelin,space between axons and myelin,lamellar separation and degeneration also were revealed in the rabbits of the experimental group after injection of TA.Peribulbus adipose tissue was near normal both by optical microscope and transmission electron microscope in the experimental group.Conclusions The periocular injection of TA dose not elevated the IOP.However,it will result in the histogical and ultrastructural damages of extraocular muscles,lacrimal gland and optic nerve.

Background Exfoliation syndrome is a systemic disease with abnormal accumulation of extracellular matrix.Oxidative stress and imbalance between matrix metalloproteinases(MMPs) and tissue inhibitor of matrix metalloproteinases(TIMPs)may play an important role in the pathogenesis of exfoliation syndrome.Researches showed that the incidence of exfoliation syndrome is higher in Uyghur nationality than that in Han nationality.However,whether the imbalance of serum MMPs and TIMPs is associated with pathogenesis of different ethnic groups is unclear.Objective The aim of the study was to discuss the change of serum MMP-9 and TIMP-2 in Uyghur patients.Methods This study protocol was approved by Ethic Committee of Xinjiang Medical University and followed Declaration of Helsinki.A prospective cohort study was performed.Forty Uyghur nationality (46 eyes) with exfoliation syndrome were collected from March 2012 to May 2013 in Affiliated First Hospital of Xinjiang Medical University and First People Hospital of Kashi.Forty cases(40 eyes)age-and gender-matched normal volunteers were included in the same duration.The peripheral blood was collected under the informed consent.Serum MMP-9 and TIMP-2 levels were detected by ELISA,and the results between the two groups were compared using independent samples t test.Results Slit-lamp examination found that part of pigmentation was depigmented and white dandrufflike substance attached in the pupil margin in all the patients,and stripping white dandruff-like substance was deposited in the front surface of the lens capsule which distributed in 3 zones.The pupils were disk-shaped pupil,and the surrounding area was the ring granular and the middle was transparent area without ablative material after dilation.Serum MMP-9 levels were (57.88±18.63)μg/L in the exfoliation syndrome group and (9.35±2.78)μg/L in the normal control group;serum TIMP-2 levels were (17.36±4.66) μg/L in the exfoliation syndrome group and (25.73±3.59) μg/L in the control group.The ratios of MMP-9/TIMP-2 were 3.57± 1.45 in the exfoliation syndrome group and 0.37±0.11 in the control group,with statistically significant differences in serum MMP-9 and TIMP-2 levels as well as ratio of MMP-9/TIMP-2 between the two groups(t=11.52,-6.36,9.87,all at P=0.00).Conclusions The upregulation of serum MMP-9 and downregulation of serum TIMP-2 are found in Uyghur patients with exfoliation syndrome.It is verified that the imbalance of serum MMP-9 and TIMP-2 contributes to the pathogenesis of exfoliation syndrome in Uyghur patients.

Background Exfoliation syndrome (XFS) is a systemic disease with abnormal accumulation of extracellular matrix.Researches showed that the single nucleotide polymorphisms (SNPs) of lysyl oxidase-like 1 (LOXL1) gene is associated with the pathogenesis of XFS in global population.However,the results are varied among different ethnicity and regions.Objective This study aimed to assess the association between LOXL1 gene polymorphisms and XFS in Uygur population.Methods One-hundred and fifty-two Uygur XFS patients without relativeness were enrolled from January to August in 2014,and 228 ethnicity-and gender-matched normal controls were recruited at the same period from the same region.Each individual underwent comprehensive eye examinations and 5 ml peripheral blood was collected.Genomic DNA was extracted from peripheral blood.PCR-ligase detection response (LDR) was used to determine the allele and genotype frequencies of the six SNPs rs12914489,rs4886467,rs4558370,rs4461027,rs4886761 and rs16958477 in the promoter region of LOXL1 gene.The distribution frequency between the patients and normal controls was compared by x2 test.Logistic regression analysis was used for age adjustment.This study was approved by Ethic Committe of Xinjiang Medical University,and informed consent was obtained from the subjects.Results rs12914489 site in the normal control group diverged from Hardy-Weinberg equilibrium (HWE) (P =0.033),and the rs4886467,rs4558370,rs4461027,rs4886761 and rs16958477 sites followed HWE.The frequencies of G allele and GG genotype of rs4886467 in the XFS group were lower than those in the control group (both at P =0.00) and were protective factors of XFS (OR =0.54,95 ％ CI:0.40-0.74,P =0.000;OR=0.51,95％ CI:0.33-0.78,P=0.001);the frequencies of T allele and TT genotype of rs4558370 in the XFS group were significantly higher than those in the control group (both at P=0.00) and were the risk factors of XFS (OR=1.96,95％ CI:1.23-3.11,P =0.004;OR =2.18,95％ CI:1.31-3.64,P =0.002);the frequencies of C allele and CC genotype of rs4461027 in the XFS group were significantly higher than those in the control group (both at P=0.00) and were the risk factors of XFS (OR=2.25,95％ CI:1.67-3.04,P=0.000;OR=3.06,95％ CI:1.89-4.96,P=0.000);the frequencies of T allele and TT genotype of rs4886761 in the XFS group were significantly higher than those in the control group (both at P=0.00) and were the risk factors of XFS (OR=2.44,95％ CI:1.79-3.33,P =0.000;OR =3.02,95％ CI:1.63-5.60,P =0.000);the frequencies of C allele and CC genotype of rs16958477 in the XFS group were significantly higher than those in the control group (both at P=0.00) and were the risk factors of XFS (OR =2.00,95 ％ CI:1.47-2.71,P =0.000;OR =2.37,95 ％ CI:1.31-4.27,P =0.004).Conclusions The SNPs of promoter region of LOXL1 gene are associated with hereditary susceptibility of XFS individually in Uygur population.The SNPs of rs4886467 locus are protective factor,while the SNPs of rs4558370,rs4461027,rs4886761 and rs16958477 locus are risk factors for pathogenesis of XFS.

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.

Objective:To investigate the clinical characteristics of renal injury caused by Guanxinsuhe pill(冠心苏合丸,including slander dutchanspipe root(青木香)).Methods:The clinical data of 27 patients with renal injury caused by Guanxinsuhe pill were studied.The clinical characteristics of the renal damage caused by Guanxinsuhe pill and the relationships between duration of illness,duration of taking Guanxinsuhe pill,anemia,renal atrophy and the progression of renal injury respectively were also analyzed.Results:Twenty-seven patients all taken Guanxinsuhe pill for suspicious coronary heart disease(CHD) and were diagnosed as chronic tubulointerstitial nephropathy accompanied with renal tubular acidosis,renal glucosuria and hyposthenuria after admission.Anemia was of more severity than renal dysfunction.Atrophic kidney occurred in 26 patients.The main complains were nonspecific symptoms including fatigue,anorexia,nausea,vomiting,etc.and accompanied with different degrees of chronic renal dysfunction.Twentyfour hours urinary protein excretions were 120-900 mg((490?250) mg).There were few red and white cells in uroscopy.Sixteen patients discontinuously took the Guanxinsuhe pill(one capsule,2-3 times a day) according to the pharmacopoeia for a long period.Ten patients took a dosage(two capsules,2-3 times a day) higher than that limited by the pharmacopoeia.Twenty-six patients took Guanxinsuhe pill discontinuously.One patient continuously took Guanxinsuhe pill until got renal dysfunction.The duration of taking Guanxinsuhe pill was 1-120 months(37.38?31.58),and the amount of 50-43 800 pills(4 576.00?8 830.54) were used,but the amount of pills of 3 cases was uncertain.The renal injury occurred within 30-216 months(95.41?56.74) after initiation of the drug taken.The renal injury obviously correlated with the anemia and the duration of taking Guanxinsuhe pill.Conclusion:Taking Guanxinsuhe pill can cause renal injury.The Guanxinsuhe pill dose indicated in pharmacopoeia also causes renal damage.The onset of renal injury is insidious.Most of the patients have the history of CHD and when the chronic nephropathy in most of such patients is detected,it is advanced to stage 5.The renal injury induced by Guanxinsuhe pill usually presents as chronic tubulointerstitial nephropathy,renal tubular dysfunction and anemia.Anemia is of more severity than renal dysfunction.The 24 hours urinary protein excretions of all the patients are lower than 1 000 mg daily.It is suggested to avoid taking Guanxinsuhe pill,adjust the prescription of Guanxinsuhe pill and do not use slander dutchanspipe root as an ingredient.
