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.

Taking an actual case as an example, this paper discusses how to integrate the informa-tization concept into the actual construction of the clinical skill center, and introduces the two aspects of the construction and management of the site and the daily business management. The design concept of multimedia standard room has been proposed, and the necessary teaching auxiliary facilities are chosen according to local conditions, all of which ensure the versatility and high cost performance of teaching units. Through the concept of information remote management, the problem of multimedia teaching terminal management is solved. Besides, through the information process reengineering, the daily business problems such as room management, multi-station examination and asset management have been solved, and syn-chronously a multimedia network learning platform has been built. The scheme has highlighted the charac-teristics of practical, efficient and management science and has achieved remarkable results, so it has cer-tain reference and promotion value.

Objective To evaluate cerebrospinal fluid adenosine deaminase(CSF-ADA)activity in the diagnosis of tuberculous meningitis(TMB), and to observe its dynamic changes. Methods A total of 160 patients were included and were divided into two groups: 76 cases of TBM and 84 cases of non-TBM.Among the cases of non-TBM, there were 36 cases of bacterial meningitis, 30 cases of viral meningitis and 18 cases of cryptocoocal meningitis. All the patients were measured with their CSF-ADA activity by Enzymecoupled assay(Trinder method)and 47 patients of TBM were measured again after 2 weeks' and 6 weeks'antitubercular therapy. Results were expressed as(-x)± s. Mann-Whitney U test and paired-samples t test were used. Results CSF-ADA activity in TBM group was(12.9 ±6.4)U/L, while that in the non-TBM group was(6.0 ± 4.1)U/L, the difference was of statistical significance(U = 7.860, P < 0.05). With the cutoff value of 9 U/L, the sensitivity and specificity to differentiate TBM from non-TBM was 84.21% and 83. 33%, respectively. CSF-ADA activity decreased in TBM patients after antitubercular treatment.Conclusions CSF-ADA activity can be an effective laboratory marker for early differential diagnosis of TMB with the cut-off value of 9 U/L. Dynamic changes of CSF-ADA activity may be a indicator for the effect of antitubercular treatment.

Objective To study the function and diurnal variation of hypothalamic-pituitary-adrenal (HPA) axis and hypothalamic-pituitary-thyroid(HPT) axis,and the relationship with clinical characteristics of di-urnal rhythm in depressed patients. Methods Forty-nine depressed patients met diagnostic DSM-Ⅳ criteria and thirty-eight normal controls were collected. The plasma levels of cortisol (CORT), adrenocorticotropic hormone (ACTH), T3, T4, thyroid-stimulating hormone (TSH) at 7 am and 7 pm were measured by radioimmunoassay, then the results concemed were compared among the depressed groups with and without diurnal variation and control group by multivariate analysis of variance. Results The plasma level of morning CORT, morning and evening TSH ((365.94±120.78) nmol/L; (6.24±2.47)μIU/ml; (6.68±2.42)μIU/ml; respectively) were respective-ly higher than those of control group((284.91±83.39) nmol/L; (3.82±1.75)μIU/ml;(4.01±1.69)μIU/ ml, P<0.05). The plasma levels of morning and evening T4 were significantly lower than those of control group(P <0.05). The CORT morning-evening difference variable distinguished between depressed and control group (P< 0.001),but no significant differences could be found between the depressed groups with and without diurnal varia-tion. There were no significant differences in the CORT, T3, T4, TSH morning-evening difference variable between various clinical subtypes of depressed patient (unipolar/bipolar; psychotic/nonpsychotic). Conclusion Abnormal CORT morning-evening difference variable was observed in the depressed patients compared with normal controls,and may be used as a special trait mark of depressed group.

Objective To study the clinicopathologic features and differential diagnosis of deep angiomyxoma(DAM). Methods Seven cases of DAM were collected from 2000 to 2008. All the patients were examined by microscopy and immunohistochemistry. Results 6 patients with DAM were females and 1 was male, with median age of 48.5 years. Median maximum dimension was 5.9cm, with invasive growth pattern. The tumor cells of DAM were infantile, spindle or stellate,diffuse and nodular arrangement. A distinctive histologic feature of DAM was its vascularity. Non-arborizing, thin-wall, ectastic capillaries or more commonly, small thick-wall vessels were dispersed throughout the tumor. Mast cells and extravasated red blood cells were frequently found in the stroma, immunohistochemical study showed that 7 cases were positive for vimentin, desmin, ER and PR, 5 for CD34 and SMA, and negative for S-100 and CK. Conclusion DAM is a rare soft tumor that occurs principally in the vulval and vagina region of woman. Misdiagnosis has happened frequently. Immunohistochemical staining are helpful to diagnosis for DAM, but no significance to distinguish it.
