AIM: To test the intraocular pressures and some biological parameters of Uyghur and Han healthy college students whose eyes are emmetropia, and to conduct comparisons between the two races, two genders, and the right and left eyes whether there is a difference between the two races.
●METHODS:Cross-sectional study. The vision of college students who reach the clinic with visual chart were tested; the keratorefractive power with an automatic refractor was tested; the eyes with slit lamp and ophthalmoscope were tested. The intraocular pressures of 405 cases ( 810 eyes in total ) with an automatic non-contact tonometer were tested; The anterior chamber depths, lens thicknesses, vitreous cavity lengths and axial lengths with an A/B - type ultrasound diagnostic equipment were tested; The intraocular pressures and some biological parameters of the two races, two genders, same genders of different races, and the right and left eyes were compared.
●RESULTS: The differences between Uyghur and Han college students in intraocular pressure, anterior depth, lens thickness, vitreous cavity length and axial length were statistically significant ( P<0. 05 ). The difference between Uyghur male college students and Uyghur female college students in anterior depth, axial length, keratorefractive power were statistically significant ( P<0. 05). The difference between Han male college students and Han female college students in axial length, keratorefractive power were statistically significant ( P<0. 05). The difference between the right and left eyes was statistically insignificant ( P > 0. 05 ). The differences between Uyghur male college students and Han male college students in intraocular pressure, anterior depth, vitreous cavity length, axial length and lens thickness were statistically significant (P<0. 05). The differences between Uyghur female college students and Han female college students in intraocular pressure, anterior depth and axial length were statistically significant (P<0. 05).
● CONCLUSION: Compared with Uyghur college students, Han college students are higher in intraocular pressure, deeper in anterior depth, longer in vitreous cavity length and axial length, and thinner in lens thickness. Compared with female college students of same race, the male college students are longer in axial length and smaller in keratorefractive power. Moreover, Uyghur male college students are deeper than Uyghur female college students in anterior depth. Compared with Uyghur male college students, Han male college students are higher in intraocular pressure, deeper in anterior depth, longer in vitreous cavity length and axial length, and thinner in lens thickness. Compared with Uyghur female college students, Han female college students are higher in intraocular pressure, deeper in anterior depth, and longer in axial length.

The purpose of this study was to construct expression vectors of idiotype (Id) SmIg in patients with B-chronic lymphocytic leukemia and to express them in E.coli to obtain recombinant Id, and to investigate the effect of the protein on the proliferation and secretion of IL-2 and IFN-gamma of stimulated peripheral blood mononuclear cells (PBMC) in vitro. Light chain gene and Fd fragment of heavy chain gene were inserted into fd-tet-DOG2 vector to construct fd-tet-DOG2-Fab. Fab gene was further cloned into expression vector pHEN2 to construct the soluble expression vector pHEN2-Fab. After induction by IPTG, Fab protein was purified by Ni-NTA-chromatography. MTT was used to determine the effects of purified protein on the proliferation of stimulated PBMC in vitro and the concentrations of IL-2 and IFN-gamma in the culture supernatants were detected by ELISA. The results showed that recombinant pHEN2-Fab expression vector was constructed successfully. Fab protein was expressed in positive clone after induced by IPTG and two specific bands at 24-25 kD position were observed by SDS-PAGE electrophoresis. Proliferation of PBMC could be induced by purified Fab and the concentrations of IL-2 and IFN-gamma in culture supernatants were increased significantly after induction. It was suggested that the expression vector of SmIg Fab fragment was constructed successfully, and expressed and secreted from E. coli. The Fab protein could induce proliferation of PBMC and promote secretion of IL-2 and IFN-gamma.

Objective To investigate the effects of angiotensin Ⅱ on nuclear transcription factor-кB(NF-кB)and interleukin-8(A549 cells),and to explore the underlying mechanisms of ventilator-induced lung injure. MethodA549 cells were maintained in Dulbecco' s modified Eagle's culture medium at 37℃ with 5 % CO2 incubator. The cells were randomly (random number) divided into 4 groups (n =24 in each). The group A was control group. The group B,C and D had A549 cells co-incubated with Angiotensin Ⅱ 10-6 mmol/L (final concentration) for 1 h,2 h and 4 h, respectively. The samples of cell culture supematant,total cellular RNA and nuclear proteins were collected or extracted after culture of cells. The II-8 contents in cell culture supernatant were detected with enzyme linked immunosorbent assay(FLISA) .The expressions of IL-8 mRNA were measured by reverse ttanscription-polymerase chain reaction (RT-PCR).The NF-κB activities were assayed with electrophoretic mobility shift assay (EMSA). The levels of NF-κB p65 subunit were detected with Western blot. The overall differences were compared by using analysis of variance(ANOVA). Differences between two groups were assessed by q tests. ResultsThe levels of IL-8 content in cell culture supematant in groups A, B, C and D were (29.59+8.36) pg/mL,(135.35 + 28.93) pg/mL,(357.12+ 57.21) pg/mL,and (1732.13+ 261.73) pg/mL,respectively(group A vs. group B, P <0.01; group B vs group C, P <0.01;group C vs. group D, P < 0.01 ) The overall differences between gtoups were statistically significant ( F =58.41,P < 0.05). The expressions of IL-8 mRNA in groups A, B, C and D were (0.13±0.03)Au·nm,(0.49+0.08) Au·mm,(0.71 ±0.10) Au·mm and (0.88±0.11) Au·mm,respectively (group A vs. group B, P <0.01; group B vs. group C, P < 0.01; group C vs. group D, P < 0.05. The overall differences between groups were statistically significant (F = 19.08, P < 0.05). The NF-κB activities in groups A, B, C and D were (70.37±6.57) Au·mm,(139.76± 11.72) Au·mm,(198.90± 18.95)Au·mm and (388.73±26.27) Au·mm, respectively (group A vs. group B, P <0.01,group B vs. groupC, P <0.05; group C vs. group D, P < 0.01 ). The overall differences between groups were statistically significant ( F = 23.15, P < 0.05). The levels of NF-κB p65 subunit in groups A, B< C and D were (33.05±6.23) Au·mm, (73.97 ± 5.34) Au·mm,(168.72± 8.40)Au·mm and (254.63 + 12.2) Au·mm, respectively (group A vs. group B, P <0.01; group B vs. group C, P <0.01; group C vs. group D, P <0.01). The overall differences between groups were statistically significant (F = 16.33,P < 0.05). Conclusions The Ang Ⅱ can significantly activate the NF-κB system and up-regulate the expression of IL-8 in human lung adenocarcinoma cell line, which cause neutrophil infiltration and activation. This effect is time-dependent and induces acute lung injure, playing an important role in the underlying mechanisms of ventilator-induced lung injure.

Objective:To explore the association of its polymorphism of TFRC with the susceptibility, clinical and pathologic phenotypes of IgA nephropathy. Methods: A total of 380 patients with IgA nephropathy and 250 normal controls were enrolled in the study. The regions with 424G/A and -5184C/T polymorphism sites of TFRC were amplified by PCR from genomic DNA and then the PCR-RFLP were performed by restriction enzymes, BanⅠ and BsmA Ⅰ, respectively. The genetic association of genotypes with the clinical and pathologic phenotypes was analyzed. Results: The distribution of frequency in TFRC was consistent with Hardy-Weinberg equilibrium; however, we found no significant difference in genotypes distribution between patients and controls. There were no differences between genotypes in age, blood pressure, 24 h urine protein excretion, serum creatinine, creatinine clearance and serum IgA. 424G/A and -5184C/T polymorphisms were associated with immunofluorescent intensity of IgA deposit in mesangial area, though there was no difference in pathological lesions evaluated by HAAS grade. Conclusion: The polymorphisms of TFRC in 424G/A and -5184C/T sites were not associated with susceptibility to IgA nephropathy, but associated with density of immunofluorescence of IgA in mesangium in our large population based Chinese patients. The association of IgA nephropathy and other polymorphism sites, as well as interaction between TFRC polymorphism and other genes' polymorphisms, neededs to be further investigated.
