Abstract?AIM:To evaluate the pupil light reflex in patients with primary open angle glaucoma, and to investigate the relation between pupil and visual field defect.?METHODS:From July 2014 to October 2015, 115 eyes in 86 patients with primary open angle glaucoma and 23 eyes in 16 healthy individuals were continuously enrolled in this study.All the subjects received comprehensive eye examination, visual field examination ( Humphrey, SITA Standard 24-2 ) and dynamic pupil measurement ( MonCV3 Metrovision) .According to the visual field and the Glaucoma Staging System, the patients with glaucoma were divided into 5 subgroups: stage 1, stage 2, stage 3, stage 4 and stage 5. The parameters of pupillary light reflex were as follows: pupil diameter ( minimum, maximum ) , latency and duration of contraction, latency and duration of dilatation, contraction amplitude, contraction and dilatation speed, and percent of pupil contraction ( PPC ). SPSS 19.0 statistical software was used to analyze the measurement results.?RESULTS:The control group significantly differed from the stage 4 subgroup ( P=0.032 ) and stage 5 subgroup (P=0.014) in terms of minimum pupil diameter; there was significant difference in the pupil contraction speed between groups ( F =648.675, P <0.01 ), and the contraction speed in stage 5 subgroup was significantly lower than those in the other subgroups and control group (P<0.05); the control group significantly differed from the stage 3, stage 4, and stage 5 subgroup in terms of PPC ( P<0.05 ).Pupil contraction speed, PPC and minimum diameter showed correlation with the stages of glaucoma.?CONCLUSION:Pupil contraction ability in patients with primary open angle glaucoma was impaired, and the degree of impairment is related with the degree of visual field defect.

OBJECTIVECigarette smoke extract (CSE) can induce injuries of pulmonary II epithelial cells, activate nuclear factor-kappaB and increase tumor necrosis factor-alpha(TNF-alpha) secretion. This study aimed to investigate whether azithromycin can protect pulmonary II epithelial cells from injuries induced by CSE and relevant mechanisms.
METHODSPulmonary II epithelial cells (A549 cells) were cultured in vitro. After 48 hrs of culture the cells were randomly treated with serum-free DMEM only (blank control group), azithromycin + serum-free DMEM, CSE+ serum-free DMEM or CSE+azithromycin. Eight hours later the morphology of A549 cells, the activity of NF-kappaB and the levels of TNF-alpha were measured by inverted microscope, immunohistochemistry and ELISA.
RESULTSThe morphology and structure of A549 cells were changed, NF-kappaB activity increased (dark brown staining ) and TNF-alpha levels (0.307 +/- 0.036 pg/mL vs 0.234 +/- 0.028 pg/mL)increased in the CSE+ serum-free DMEM group compared with the blank control group (P < 0.01). CSE together with azithromycin treatment recovered partly the morphological injuries of A549 cells. It also attenuated NF-kappaB staining and decreased TNF-alpha levels from 0.307 +/- 0.036 pg/mL (CSE+serum-free DMEM group) to 0.269 +/- 0.009 pg/mL (P < 0.05).
CONCLUSIONSAzithromycin may inhibit NF-kappaB activity, decrease TNF-alpha secretion and thus lessen cytotoxicity of CSE to A549 cells.

OBJECTIVETo study the clinical outcome, adverse effect and treatment cost of homoharringtonine (HHT) in combination with all-trans retinoic acid (ATRA) and arsenic trioxide (AS2O3) for newly diagnosed with patients acute promyelocytic leukemia (APL).
METHODSClinical data of treatment of newly diagnosed patients with APL in experimental group (HHT + ATRA + AS2O3, n = 14) and control group \[Idarubicin (IDA) + ATRA + AS2O3, n = 21\] were analyzed retrospectively. The therapeutic effects, side effects and costs during induction therapy were compared between the two groups.
RESULTS(1) The complete remission (CR) rate were 92.9% (13/14) and 95.2% (20/21) in experimental group and control group, respectively. The time to achieve CR were (28.1 ± 3.8) and (31.7 ± 4.2) days, respectively (P > 0.05). The negative rate of PML-RARα fusion gene at the time of CR were 76.9% (10/13) and 75.0% (15/20), respectively, and that in CR patient at the end of the first cycle treatment were 100.0% (13/13) and 95.0% (19/20), respectively (P > 0.05). (2) 5-year overall survival (OS) rate were (92.6 ± 0.6)% and (89.9 ± 0.5)%, respectively (P > 0.05), 5-year disease free survival (DFS) rate were 100.0% and (86.8 ± 0.6)%, respectively (P > 0.05). (3) During induction therapy, the incidence of infection in experimental and control group were 23.1% (3/13), 60.0% (12/20), respectively (P < 0.05). The amount of platelet transfusion were (54.7 ± 29.6) and (76.5 ± 25.6) units, respectively (P > 0.05), and that of fresh frozen plasma were (1157.1 ± 238.4) and (1423.5 ± 324.6) ml, respectively (P > 0.05). The total medical costs (excluding HHT and IDA) in experimental and control group were (36074.9 ± 1245.6) and (50564.5 ± 3658.4)CNY, respectively (P < 0.05).
CONCLUSIONHHT in combination with ATRA and AS2O3 regimen for newly diagnosed APL has a better efficacy, a higher long-term survival rate, and a lower costs, which is one of the reasonable choice.

OBJECTIVETo find a convenient and exact method for evaluating acrosome reaction in human spermatozoa.
METHODSThe semen of the normal male was mixed and then divided into 6 groups. Coomassie brilliant blue (CBB) staining, chlortetracycline (CTC) fluorescence staining and acid phosphatase (ACP) detection were used for morphological observation and data analysis of the acrosome status of the human sperm treated with or without progesterone.
RESULTSThere were obvious morphological differences between the acrosome-reaction and acrosome-intact spermatozoa in CBB staining and CTC fluorescence staining, and significant differences were observed between the experimental and control spermatozoa by the three methods (P < 0.05).
CONCLUSIONAll the three methods can be used to assess acrosome reaction in human spermatozoa, but Coomassie brilliant blue (CBB) staining is much more convenient and stable.
