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. There is no difference between the right and left eyes.

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 compare and analyze the clinical efficacy of locking plates versus artificial joint replacement for proximal humeral complicated fractures.Methods The retrospective data of 200 cases with locking plate or artificial joint replacement for the treatment of comminuted proximal humeral fractures were collected from February 2013 to July in our hospital.Patients were divided into locking plate group (n =114) and artificial joint replacement group (n =86) according to the treatment.The pain,functional recovery,activity,anatomical position,complications and Neer score after treatment were compared between the two groups.Results In artificial joint replacement group,Neer score was excellent in 34 cases,good in 23 cases,fair in 25 cases,poor in 4 cases,and the excellent and good rate was 66.3％ (57/86).In locking plate group,Neer score was excellent in 53 cases,good in 47 cases,fair in 10 cases,poor in 4 cases,and the excellent and good rate was 87.7％ (100/114).The excellent and good rate was higher in locking plate group than in artificial joint replacement group (x2 =13.35,P＜0.001).The scores of pain,functional recovery,activity and anatomical position were (26.9 ± 8.5),(22.4 ± 7.1),(19.8 ± 5.5) and (8.0 ± 1.8) respectively in locking plate group,and (24.8±10.2),(20.2±6.7),(18.1±6.6) and (7.9±2.1) respectively in artificial joint replacement group.There were significant differences in scores of functional recovery and activity between groups (t＝ 2.22 and 1.99,P =0.014 and 0.024),while no significant differences were found in scores of pain and anatomical position (t=1.59 and 0.36,P＝0.057 and 0.359).There were 2 cases with ankylosis,1 case with malunion and 1 case with humeral head necrosis in locking plate group,and 1 case with ankylosis,1 case with wound infection,1 case with refracture and 1 case with humeral head necrosis in artificial joint replacement group after treatment.There were no significant differences in complications between groups (x2 =0.17,P=0.683).Conclusions The locking plate and artificial joint replacement are effective in the treatment of comminuted proximal humeral fractures.Compared with artificial joint replacement,the locking plate can improve the functional recovery,activity and Neer score evaluation with a low technical requirement,which is an ideal method for comminuted proximal humeral fractures.

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 pre-hospital delay factor of coronary reperfusion therapy for ST-elevation acute myocardial infarction (STEAMI) patients presenting with non-chest pains. Methods A retrospective observation was conducted. The clinical data of STEAMI patients underwent emergency percutaneous coronary intervention (PCI) admitted to Luoyang Central Hospital Affiliated to Zhengzhou University from August 2013 to August 2015 were analyzed. The patients were divided into chest pain group and non-chest pain group according to the presence of chest pain or not. Clinical characteristics were compared between the two groups, and incidence of major adverse cardiac events (MACE), door-to-balloon time, door-to-electrocardiograms (ECG) time and ECG-to-balloon time were evaluated. Influencing factors of pre-hospital delay was analyzed by logistic multiple stepwise regression. Results A total of 259 patients with STEAMI were enrolled, including 154 patients with chest pain and 105 presented with non-chest pains. Compared with chest pain group, the patients in the non-chest pain group were older (years: 68.12±8.93 vs. 62.34±7.12, P < 0.05), less female (26.67% vs. 42.20%, P< 0.05), and had a higher past history of angina, stroke and heart failure (27.61% vs. 13.63%, 31.42% vs. 18.83%, 26.67% vs. 11.68%, respectively, all P < 0.05), and higher percentage of Killip ≥ Ⅲ patients (15.24% vs. 6.49%, P < 0.05), the lower ambulance use (26.67% vs. 44.81%, P < 0.01), longer hospitalization time (days: 12.50±2.89 vs. 9.50±2.67, P < 0.05), higher incidence of MACE (19.05% vs. 9.09%, P < 0.05), longer door-to-balloon time and door-to-ECG time (minutes: 159.01±51.21 vs. 115.31±36.74, 53.06±18.17 vs. 30.35±9.93, both P < 0.01). It was shown by logistic multivariate regression analysis that no-chest pain [odds ratio (OR) = 5.14, 95% confidence interval (95%CI) = 2.34-10.81, P < 0.001], age ≥ 65 years old (OR = 1.43, 95%CI = 0.93-2.99, P = 0.022), diabetes (OR = 1.57, 95%CI = 0.66-2.15, P = 0.015) and no-ambulance transport (OR = 1.55, 95%CI = 0.73-2.75, P < 0.001) were risks factors of coronary reperfusion delay ≥ 2 hours. Conclusions STEAMI patients presenting without chest pain showed higher incidences of MACE, longer time of ECG obtained and initial PCI time delay. Clinicians should try to reduce the delay time of the patients in order to improve patient survival rates.
