At T_2 the poorly ventilated lung accounted for 22.9%?5.0%,but there was no atelectasis.There was no atelectasis and poorly ventilated lung at T_3 and T_4.At T_5 atelectasis accounted for 4.5%?1.1% which was reduced to 0.9%?0.4% at T_6.Conclusion Breathing 100% oxygen at reduced lung volume can result in atelectasis.

Objective To analyze the examination results of external quality assessment(EQA) at all levels of iodine deficiency disorders(IDD) laboratories in Henan province and the network operation to further standardize and improve the laboratory,and to provide reliable laboratory quality assurance for surveillance and control of IDD.Methods The examination results of EQA at all levels of IDD laboratories in Henan province were statistically analyzed in accordance with the National Reference Laboratory (NRL) of IDD (1999-201 1).Results The survey results showed that the provincial level laboratory was all qualified in testing urinary iodine and salt iodine in the past 13 years.In prefectural level,the laboratory response rates were 100.0％,and through participation in EQA,laboratory capacity had been significantly increased and stabilized.From 1999 to 2001,the passing rate of check up of urinary iodine was 22.2％ (4/18),72.2％ (13/18),94.4％ (17/18),respectively,and the rate was stable at 100.0％(18/18) from 2002 to 2011 except 94.4％ (17/18) in 2003.Since 2000,the prefectural level laboratory began to take part in the salt iodine EQA,and the laboratory response rate was 100.0％ (18/18) from 2000 to 2011.Except 88.9％(16/18) in 2003,the passing rate of check up of urinary iodine was 100.0％(18/18)from 2000 to 2011.In 2003 and 2004,6 to 7 county-level laboratories participated in the EQA of urinary iodine in Zhengzhou city,respectively,and all qualified.The number of county-level laboratories that participated in the salt iodine quality control network increased from 29 in 1999 to 148 in 2011.Response rate was 94.4％(68/72),96.7％(58/60) and 92.3％(144/156)in 2003,2006 and 2007,respectively,and the rate remained stable at 100.0％ in the remaining 10 years.In 1999,the passing rate was 69.0％ (20/29),then increased significantly,except 86.7％ (26/30) in 2001 and 84.6％(132/156) in 2007,the rates were all above 90.0％ in other years,especially in 2000 and 2009,the passing rates were both 100.0％.Conclusions The accuracy of test results of external quality controls and the normal operation of the network at all levels of laboratories is closely related to the IDD laboratory conditions and detection techniques.

Background About one third of congenital cataract is associated with inheriting factor.The inherited heterogeneity has been found in congenital cataract.To seek the pathogenic gene is essential for the gene therapy. Objective Present study was to map and identify the causal gene for autosomal dominant congenital cataract (ADCC) in a Chinese family. Methods The clinical features of all affected members in this family were examined.Blood samples were collected from eleven family members for genetic linkage analysis.Polymorphic microsatellite markers were selected from the regions which harbor all known loci linked with ADCC.Universal fluorescent-labeled M13 primer was used in linkage analysis.Direct genomic sequencing was used to evaluate the candidate gene for example CRYBB2 gene.This study followed Helsinki Declaration and was proved by Tianjin City Ethic Committee.Written informed consent was obtained from each SUbject before any medical procees. Results The maximum two-point LOD score of 1.20 was obtained for marker D22S315 (θ=0).The LOD score of 0.6 was obtained for marker D16S3068.No mutation in all exons of CRYBB2 gene was found in the family. Conclusion CRYBB2 gene associated with ADCC was excluded from the family.A genome-wide linkage screening should be conducted.Genotyping with microsatellite markers using Universal fluorescent-labeled M13 primer can decrease the cost and obtain the same result.

AlM:To investigate the influence of phacoemulsification with different incision on tear film.
METHODS:Tear film was monitored in 152 patients (169 eyes) after phacoemulsification. Patients were divided into two groups according to the type of incision:group A (76 patients, 83 eyes) with a 3. 2mm corneoscleral limbus incision phacoemulsification and group B (76 patients, 86 eyes ) with a sclemtic tunnel incision. Tear break-up time ( BUT ) , cornea fluorescein staining ( CFS ) , lid-parallel conjunctival folds ( LlPCOF) and lid-wiper epitheliopathy ( LWE ) were observed at 3d preoperatively and 1wk, 1, 3 and 6mo postoperatively. The results were analyzed using a Chi-square test and t-test with SPSS 17. 0.
RESULTS:BUT: The BUT of two groups was obviously shorter at 1wk, 1mo postoperatively, the differences were statistically significant (P<0. 05), however, there were no statistically significant at 3, 6mo(P>0. 05). CFS score:There was a large increase in CFS at 1wk, 1mo postoperatively, the differences were statistically significant between the two groups(P<0. 05), however, there were no statistically significant at 3, 6mo (P>0. 05). LlPCOF:There was a large increase in LlPCOF at 1wk, 1 and 3mo postoperatively, the differences were statistically significant between the two groups (P<0. 05), however, there were no statistically significant at 6mo (P>0. 05). LWE: There was a large increase in tear osmolarity at 1wk, 1mo postoperatively. The differences were statistically significant between the two groups (P<0. 05), however, there were no statistically significant differences between the two groups at 3, 6mo (P>0. 05).
CONCLUSlON:The stability of tear film in patients with scleral tunnel incision is much better than in patients with 3. 2mm corneoscleral limbus incision phacoemulsification. There is no significant difference between the two groups during later postoperative periods.
