BACKGROUND: Cytokine is a poly-functional and effective regulator factor to regulate growth of multiple cells. Researches suggest that, as an inflammatory medium, cytokines play a key role in inflammatory reaction of eye; however, there are rare studies on dynamic changes after traumatic cataract.OBJECTIVE: To investigate the relationship among inflammatory reaction and dynamic changes of interleukin 1 (IL-1),IL-6 and tumor necrosis factor alpha (TNF-α) in aqueous humor of rabbits after extracapsular cataract extraction.DESIGN: Randomized controlled animal study.SETTING: Shenzhen Municipal Ophthalmology Hospital, Shenzhen Municipal Ophthalmology Center Affiliated to Medical College of Jinan University.MATERIALS: The experiment was carried out in Institute of Shenzhen Municipal Ophthalmology Center Affiliated to Medical College of Jinan University from March 2004 to March 2006. Fifteen healthy adult New Zealand rabbits of 30 eyes,general grade, weighting 2.5-3.0 kg, of either gender, were provided by Animal Center of the Second Clinical Medical College of Jinan University [certification: SYXK (yue) 2005-006]. Eyes of rabbits were normal before experiment. All rabbits were randomly divided into normal control group, traumatic control group and operative group with 5 in each group and in total of 10 eyes in each group. IL-1, IL-6 and TNF-α kits were provided by Shenzhen Yawei Biotechnology Company Limited.METHODS: Rabbits in traumatic control group and operative group were totally anesthetized with intravenous injection of 10% 1 mi/kg urethan, and then, 5# needle was punctured from corneal limbus to anterior chamber to scarify anterior membrane of lens about 5 mm to establish animal models of traumatic cataract of oculus uterque. Rabbits in normal control group were fed normally. After successful modeling, common antibiotic eyedrops was used to clean conjunctival sac of rabbits in traumatic control group and operative group 3 times a day. On the 3rd day of successful modeling, rabbits in operative group were totally anesthetized with intravenous injection of 10% 1 mL/kg urethan, and then, they undertook extracapsular cataract extraction of oculus uterque: horizontally intercepting bladder or waterly separating with breakage of anterior bladder membrane, expulsing nucleus of lens, washing lens cortex and suturing incisions. On the operative day and on the 1st, 3rd, 7th and 14th days after operation, inflammatory reaction of anterior chamber in traumatic control group and operative group was measured and 0.2 mL aqueous humor was extracted from rabbits in three groups to count and classify cells; meanwhile, expressed level and dynamic changes of IL-1, IL-6 and TNF-α in cytokines of aqueous humor were measured with double-antibodies ELASA technique.MAIN OUTCOME MEASURES: Total numbors of leucocytes and contents of IL-1, IL-6 and TNF-α in aqueous humor of rabbits in three groups after operation.RESULTS: ① On the 1st, 3rd, 7th and 14th days after operation, numbers of leucocytes were (2.4±0.7)×106/L, (2,2±0.5)×106/L, (2.8±0.8)×106/L and (2.0±0.5)×106/L in aqueous humor; (19.7±7.3)×106/L, (28.1±9.6)×106/L, (14.2±5.6)×106/L and(8.4±3.8)×106/L in traumatic control group; (65.3±14.5)×106/L, (79.8±12.7)×106/L, (21.7±8.2)×106/L and (12.4±4.1)×106/L in operative group. In addition, numbers of leucocytes were more in traumatic control group and operative group than those in normal control group (F =22.5, 27.9, 11.6, 8.4;P<0.05). ② Within 1-14 days after operation, contents of IL-1, IL-6and TNF-α in aqueous humo were higher in traumatic control group and operative group than those in normal control group (P<0.05), and there was a significant difference between traumatic control group and operative group (P<0.05);however, there was no significant difference among three groups on the operative day (P>0.05). ③ Contents of cytokines reached peak on the 7th day after operation, decreased gradually, and reached the lowest value on the 14th day.Contents in traumatic control group and operative group were higher than those in normal control group (P<0.05).CONCLUSION: The intraocular inflammation after lens extraction is closely related to the dynamic changes of IL-1, IL-6and TNF-α levels in aqueous humor. Cytokine may be one of crucially inflammatory agents in the eyes after traumatic cataract.

Objective To evaluate the value of nuchal translucency (NT) thickness in the fetal chromosome abnormality screening. Methods 11 086 pregnant women received NT measurement in 11 ~ 13+6 weeks at Hainan general hospital from January 2010 to December 2014 were selected in the study. The NT thickness was measured according to guidelines from Fetal Medicine Foundation. 122 fetuses (NT≥2.5 mm) were recruited to accept karyotype analysis. Results 11 086 pregnant women received NT measurement in 11 ~13+6 weeks, in which 122 cases′ NT are more than or equal to 2.5 mm, with a positive rate of 1.10%. 122 cases of fetal NT thickening are between 2.5 to 12.0 mm, with the average degree at (4.5 ± 2.1)mm. 122 invasive prenatal diagnostic specimens chromosome karyotype analysis results showed chromosomal abnormalities in 21 cases (abnormal rate of 17.2%), the abnormal chromosome number in 17 cases and abnormal structure in 4 cases. The top 3 are trisomy 21 (12 cases, 57.1%), chromosome pericentric inversion (3 cases, 14.3%), and trisomy 18 (2 cases, 9.5%). Fetal chromosomal abnormalities resulting from different childbirth age, the sex of the fetus, NT thickness showed significant statistical difference (P < 0.05). The concrete manifestation is that fetal chromosomal anomaly detection rate in childbirth by women more than 35 years old age are higher than other age. Female fetal chromosomal anomaly detection rate is higher than the male , and NT thickness of 5mm of fetal chromosomal abnormality rate is significantly higher than the thickness of NT group at 2.5mm~ and 3.5mm~. Fetal NT thickening of NT measurements was in significant positive correlation with fetal chromosome abnormal rate (χ2=15.533, P < 0.001). Logistic regression analysis found that with a higher NT thickness , risk of fetal chromosomal abnormalities would be significantly higher , and thickening of NT could be an independent predictor of fetal chromosome abnormalities. Conclusion In early pregnancy, ultrasound examination of fetal ultrasound screening of NT thickness can be used as an important index of fetal chromosomal abnormality , and interventional diagnosis of prenatal NT thickness increase could pose increased risk of fetal chromosomal abnormalities.
