Objective To evaluate the repeatability and agreement of two optical biometers (Lenstar LS900 (R) and SW-9000) for ocular biometry in Chinese adolescents.Methods A prospective study was conducted which included 65 ametropic patients,with an average age of (11.45 ± 2.67) years (age ranging from 8 to 18 years).The ocular biometry for right eyeball was performed with Lenstar LS900 (R) and SW-9000 respectively,followed by evaluation of the repeatability of the two biometers using one-way analysis of variance,and the agreement of the two instruments using the Bland-Altman plot.Results The repeatability of parameters measured by Lenstar LS900 (R),including axial length (AL),K value in the flattest meridian (K1),K value in the steepest meridian (K2),central corneal thickness (CCT),anterior depth (AD),lens thickness (LT),pupil diameter (PD),was well,and all intraclass correlation coefficient (ICC) ＞ 0.9;the repeatability of white to white (WTW) was inferior to other parameters,but it was still ＞0.88.The repeatability of AL,K1,K2,CCT measured by SW-9000 was good,with their ICC ＞ 0.9,but the repeatability of other parameters was poor.The parameters with good repeatability including AL,K1,K2,CCT measured by SW-9000 and Lenstar LS900 (R) were compared respectively,and the results showed that AL and CCT examined by SW-9000 were slightly longer than those measured by Lenstar LS900 (R),and the difference was statistically significant (all P ＜ 0.05).However,there was no significant difference about K1,K2 (all P＞0.05).Moreover,the AL,K1,K2 and CCT measured by the two instruments had close linear correlation (all r ＞0.97,all P ＜0.01).The BlandAltman plot showed that 95％ LoA (limits of agreement) of AL was (-0.057 to 0.133) mm,K1 was (-0.456 to 0.369) D,K2 was (-0.388 to 0.549) D and CCT was (-3.483 to 8.016) μm.Conclusion Biometric parameters including AL,K1,K2,CCT measured by Lenstar LS900 (R) and SW-9000 have good repeatability in the adolescents aged 8-18 years and they are highly correlated;meanwhile,the agreement of AL,K1,K2,CCT measured by SW-9000 with Lenstar LS900 (R) is acceptable in clinical practices.

Objective To investigate the clinical significance of I-FISH for detection of genomic abnormalities in MM. Methods Twenty newly diagnosed MM patients(seven cases at stage Ⅰ , five cases at stage Ⅱ and eight cases at stage Ⅲ according to Bataille staging) were analyzed by combining the technique of CC (R-binding stain) and I-FISH [ including GLP13q14 (RBI gene), GLP17p13. 1 (P53 gene),GLP13q14. 3(D13S319) ,GLP1q21 ,GLP14q32(IgH gene) DNA sequence probes]. These two methods were compared for the detection rates of chromosomal and genomic abnormalities in MM and the association between genomic abnormalities and Bataille stages was also analyzed. Results CC examination showed only 1 case [5% (1/20) ] was found complex chromosomal abnormalities--46,XX,-2,del(3) (p21) ,add(6)(q26) ,der(10)(q26),der(14)(q32), + mar, inc[6]. While I-FISH assay showed that 12 cases [60%(12/20) ] were found genomic abnormalities. The frequencies of RB1, D13S319 and P53 were all 30%(6/20), and the frequencies of IgH gene and 1q21 were both 20% (4/20). The detection rate of the I-FISH was much higher than CC (χ2 = 9. 09, P = 0. 001) according to paired χ2 test. Of 20 patients,6 cases had RB1 gene abnormality, 1 case at stage Ⅰ , 2 cases at stage Ⅱ and 4 cases at stage Ⅲ. Of 20 patients, 6 cases had D13S319 gene abnormality, 2 cases at stage Ⅰ , 1 case at stage Ⅱ and 3 cases at stage Ⅲ. Of 20 patients, 6 cases in 20 had P53 gene abnormality, 2 cases at stage Ⅰ and 4 cases at stage Ⅲ. Of 20 patients, 4 cases had 1q21 gene abnormality, 2 cases at stage Ⅰ and 2 cases at stage Ⅲ. Of 20 patients, 4 cases had IGH gene abnormality, 1 case at stage Ⅰ and 3 cases at stage Ⅲ. Conclusion Ⅰ-FISH has higher detection rate for the genomic abnormalities in MM and can be used in detection of MM patients in different Bataille stages.

Objective To analyze the differentially expressed genes in esophageal squamons cell carcinoma (ESCC), para-cancerous tissue (PCT) and normal esophagus tissue (NET) using oligomicroarray and to identify the target genes related to the development and progression of esophageal carcinoma. Methods The total RNAs isolated from ESCC, PCT or NET using one step Trizol method were purified and reversely transcribed into cRNAs. The cRNAs were then fluorescence labeled and hybridized with Agilent oligomicroarray (21 074 probes). The fluorescence intensity features were detected by Agilent scanner and quantified by feature extraction software. The selected candidate genes were confirmed by real time real time fluorescent quantitative RT-PCR immunohistochemistry andWestern blotting.Results ① The oligomicroarray demonstrated that there were 38 up-regulated genes and 61 down-regulated genes. ② The real time fluorescent quantitative RT-PCR revealed that five genes (CTHRC1, INHBA, SPP1 ,LUM, HRK)were more differentially expressed in up-regulated genes. Of which, CTHRC1 displayed more disparity.③ Immunohistochemistry examination showed that the higher expression of CTHRC1 (56.5 %, 26/46) was observed in ESCC. There was significantly difference in expression of CTHRC1 between patients with or without lymph node metastasis (P<0.05). ④ CTHRC1 protein was expressed in both TE-13 and Eca-109 cell lines. Conclusion CTHRC1 is probably one of the most significant biomolecules in ESCC.

Objective To investigate the expression levels of TAK1 and p38 genes among different subtypes of acute myeloid leukemia (AML) patients,and to analyze the clinical characteristics of patients with different expression levels of TAK1 and p38 genes.Methods GAPDH was made as an internal reference,14 healthy people as control group.The quantitative real-time PCR was used to detect the expression of TAK1 and p38 in bone marrow samples of 87 AML patients,and the results were analyzed statistically.Results The expression levels of TAK1 and p38 in experiment group were higher than those in control group (0.194± 0.125 vs 0.015±0.008,0.233±0.140 vs 0.010±0.005,P ＜ 0.001).TAK1 expression in M4 was higher than that in M2,M3 and M5 (P =0.005,0.000,0.002),TAK1 expression in M3 was lower than that in M2 (P =0.022).p38 expression in M4 was higher than that in M1,M2,M3 and M5 (P =0.013,0.035,0.000,0.045),as it was higher in M2 and M5 than that in M3 (P =0.001,0.012).The CD56 positive rate cells and the number of peripheral blood leukocytes of the TAK1 high expression group were higher than those of the TAK1 low expression group,the CD19 positive rate of the p38 low expression group was higher than that of the p38 high expression group.Conclusion The expression levels of TAK1 and p38 genes are elevated in AML patients,and the up-regulation may play an important role in the pathogenesis of AML.

Mesenchymal stem cells (MSCs) are multipotent stromal cells derived from the mesoderm that can differentiate into a variety of cell types.Recently,as the study of MSCs in the treatment of various autoimmune diseases is maturing,more and more researchers have advocated the immune function of MSCs and the treatment for dry eye.The rate of dry eye is higher.The duration of therapy in dry eye,especially immune related dry eye,is long,and the therapeutic effect is poor.Dry eye has affected people's quality of life,so it is important to find new methods to treat it.This article reviews MSCs function in dry eye.

Objective To investigate the chromosome karyotype of acute lymphocytic leukemia (ALL) and its correlation with the clinical feature and efficacy.Methods The chromosomes of bone marrow/peripheral blood from 110 cases of patients with ALL were prepared after 24 hours culture,and G-banding were used to analyze karyotypes.Results Among 110 patients with ALL,71 cases (64.5 ％) had clonal chromsomal normalities,39 cases (35.5 ％) had clonal chromsomal abnormalities,24 cases (21.8 ％) had chromosome structural abnormalities,11 cases (10.0 ％) had chromosome number abnormalities,3 cases (2.7 ％) had chromosome number and structure abnormalities,one case had chromosomal abnormalities complex karyotype.Efficacy in patients with ALL with t(9;22) (q34;q11) was worse than the other patients (Fisher s exact text,P =0.045).There was no significant difference on efficacy between in adult ALL associated with t(9;22) (q34;q11) and in children with ALL (Fisher's exact text,P =0.506).Conclusion Chromosome karyotype of ALL patients is random,chromosomal translocations such as t(9;22)(q34;q1 1) and t(4;11) (q21;q23) have poorer treatment outcomes.

Objective:To explore the relationship between contact lens (CL) related dry eye and morphological changes of meibomian glands.Methods:A cross-sectional study was performed.A total of 157 consecutive subjects (314 eyes) to underwent refractive surgery from May 2014 to June 2015 in Tianjin Medical University Eye Hospital were included.The subjects wearing soft CL for a long time were divided into CL group (182 eyes of 91 subjects), while the subjects who never wore CL were divided into the control group (132 eyes of 66 subjects). The ocular surface disease index (OSDI) questionnaire, tear meniscus height (TMH), first non-invasive tear film breakup time (fNIBUT), average non-invasive tear film breakup time (avNIBUT) and corneal fluorescein staining (CFS) score of all subjects were collected and analyzed.Morphological evaluation of meibomian glands were performed.The meibomian glands dropout ratio of upper eyelid, lower eyelid and total meibomian gland area as well as meibomian glands distortion number of the two groups were compared.This study adhered to the Declaration of Helsinki and was approved by the Ethics Committee of Tianjin Medical University Eye Hospital (No.2014KY[L]-09). Written informed consent was obtained from each patients prior to any examination.Results:The OSDI score, CFS score, TMH, fNIBUT and avNIBUT were 16.67(10.00, 25.00), 13.88(7.50, 18.26), 0.20(0.17, 0.23) mm, 5.64(3.95, 7.92)s and 8.56(6.56, 12.12)s in CL group, respectively, while 13.88(7.50, 18.26), 1.00(0.00, 2.00), 0.22(0.17, 0.29) mm, 7.33(4.54, 13.21)s and 11.49(7.46, 17.83)s in the control group, respectively.Compared with the control group, the CL group had the higher OSDI score, higher CFS score, lower TMH, lower fNIBUT, lower avNIBUT, and the differences were significant (all at P<0.01). The MG dropout ratio and meibomian gland distortion number were (29.42±12.24)% and 4(3, 6) in CL group, respectively, while (20.37±10.83)% and 3(1, 4) in the control group, respectively.In comparison with the control group, the CL group had the higher MG dropout ratio and greater meibomian gland distortion number ( t=6.76, P<0.01; U=7 656.00, P<0.01). A positive correlation was found between the total meibomian gland area dropout ratio and duration of CL wearing ( rS=0.404, P<0.01), OSDI scores ( rS=0.275, P<0.01), CFS scores ( rS=0.319, P<0.01). Conclusions:Long-term wearing of CL can lead to severe ocular discomfort, dry eye syndrome and morphological alterations in meibomian gland, suggesting that morphological abnormality of meibomian gland is presumably associated with the occurrence of ocular discomfort and dry eye syndromes in CL wearers.
