AlM: To explore the different ages of congenital nasolacrimal duct obstruction in infants, take different treatment methods at different times.
METHODS:The 87 cases of 102 children were divided into three different age groups: the first group of 25d-3mo of age 21 cases 26 eyes; The second group >3mo-7mo 31 cases 36 eyes;The third group >7-24mo of age 35 cases 40 eyes. For the first group of infants, the implementation of the lacrimal sac nasolacrimal duct massage + eye drops; for the second group of infants, carry lacrimal pressure washing treatment; for the third group of infants, the implementation of the nasolacrimal duct probing treatment.
RESULTS: The first group of children through the nasolacrimal duct sac massage + drops tobramycin eye drops treatment unobstructed 12, the cure rate was 46. 2%;The second group of children through pressurized irrigation treatment lacrimal patency by 33, the cure rate was 91. 7%; The third group of children through the nasolacrimal duct probing unobstructed 36 treatment, the cure rate was 90. 0%. The second and third group were better than the first group (χ2=15. 71, P<0. 01;χ2=15. 27, P<0. 01);the treatment effect of the second and third groups was no significant difference (χ2=0. 02, P>0. 05).
CONCLUSlON:lnfants with congenital nasolacrimal duct obstruction should distinguish between ages, taking different treatments, in order to obtain a better therapeutic effect, and lacrimal pressure washing is the preferred way of treating infants with congenital nasolacrimal duct obstruction.

Currently,three predominant subtypes of influenza virus are prevalent in pig populations worldwide:H1N1,H3N2,and H1N2.European avian-like H1N1 viruses,which were initially detected in European pig populations in 1979,have been circulating in pigs in eastern China since 2007.In this study,six influenza A viruses were isolated from 60 swine lung samples collected from January to April 2011 in eastern China.Based on whole genome sequencing,molecular characteristics of two isolates were determined.Phylogenetic analysis showed the eight genes of the two isolates were closely related to those of the avian-like H1N1 viruses circulating in pig populations,especially similar to those found in China.Four potential glycosylation sites were observed at positions 13,26,198,277 in the HA1 proteins of the two isolates.Due to the presence of a stop codon at codon 12,the isolates contained truncated PB1-F2 proteins.In this study,the isolates contained 591Q,627E and 701N in the polymerase subunit PB2,which had been shown to be determinants of virulence and host adaptation.The isolates also had a D rather than E at position 92 of the NS1,a marker of mammalian adaptation.Both isolates contained the GPKV motif at the PDZ ligand domain of the 3' end of the NS1,a characteristic marker of the European avian-like swine viruses since about 1999,which is distinct from those of avian,human and classical swine viruses.The M2 proteins of the isolates have the mutation (S31N),a characteristic marker of the European avian-like swine viruses since about 1987,which may confer resistance to amantadine and rimantadine antivirals.Our findings further emphasize the importance of surveillance on the genetic diversity of influenza A viruses in pigs,and raise more concerns about the occurrence of cross-species transmission events.

Objective To explore the effect of cutaneous never anastomosis on sensory recovery in repairing wide spreadly soft tissue defects in dorsal hand with free anterolateral femoral flap. Methods The cases with wide spreadly soft tissue defects in dorsal hand repaired with free anterolateral femoral flap from January 2006 to December 2012 were divided into 2 groups. The control group including 15 consecutive patients from January 2006 to January 2009, whose sensation was reconstructed in routine way. Other 15 consecutive patients from Febnary 2009 to December 2012 were as research group, whose sensation was reconstructed with the suture of cutaneous nevers of anterolateral femoral flaps and forearm. All the patients were followed up for 12~24 months. Results All the free flaps survived in both groups. There were 4 cases good of sensory recovery in the control group, and it was 11 in the research group. No ulceration happened. Conclusion Cutaneous never anastomosis may result in satisfactory sensory function in the patients with wide spreadly soft tissue descts in dorsal hand repaired with free anterolateral femoral flap.

Objective To analyze the failure ratio and the causes of the inoculation failure of hepatitis B virus(HBV)-vaccine in children and relevant the remedial measures. Methods One thousand three hundred and sixty cases treated in Suzhou Wuzhong people′s hospital during Jan.2007 to Jul.2008 were chosen,of whom 286 children from 1-5 years old to be anti-HBs negative or anti-HBs titre to be 0-10 IU/L were screened,and specific failure reasons for the vaccination were analyzed,also the timely treatment measures were taken.Then 286 children were divided into 5 groups randomly.Apart from one group was set up as blank control,the other 4 groups were arranged to accept different immunization methods with 0,1,2 month schedule,group A simply got revaccinated with HB vaccine(10 ?g) 3 times;group B revaccinated with double dosage of HB vaccine(20 ?g) 3 times;group C besides being revaccinated 3 times,the immune regulatory agent was jointly used;group D revaccinated 3 times with genetically engineered CHO hepatitis B vaccine. Results The ratio of failure of HBV-vaccine was 21.03%,what caused failure of hepatitis B vaccine included immunologic inadequacy 218(76.22%),repeated respiratory infection 192 cases(67.13%),abuse hormone 140 cases(48.95%),zinc deficiency 129 cases(45.10%),anaemia 108 cases(37.76%),passive smoking 80 cases(27.97%),the mother being chronic parenchymatous nephritis or HBV carrier 63 cases(22.03%),premature 54 cases(18.88%),adiposity 38 cases(13.29%),dystrophy 29 cases(10.14%).There were 4 methods of revaccination,the positive rate for group A,B,C,D were 90.00%,96.47%,99.08%,95.83%,respectively.Group C had the highest positive rate,compared with the other 3 groups,which were statistically significant(P a
