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.

A system analysis about the microbial flora of normal and abnormal soybean sauce liquor from the high-salt-level watery state fermentation was made and the dominant bacteria and yeasts were identified.On the other hand,a discussion of effect of temperature on microbial flora was made.The results indicated that there were no obvious differences about the count of aerobe,spore-producing bacteria,enterobacteriaceae,lactic acid bacteria and anaerobe between the normal and abnormal soybean sauce liquor and there were marked differences about the count of yeasts and salt-tolerant bacteria.The predominant yeasts in normal soybean sauce were Torulopsis and Saccharomyces,accounting for 55.9% and 35.3% of the total yeasts separately,and in abnormal soybean sauce were Pichia,candida and Saccharomyces,accounting for 62.8%,17.9% and 9.0% respectively.

These years with industrial antiseptics and disinfectants widely used, especially unscientifically used, the resistance of microorganisms is more and more serious, which brought much more difficulties to industrial producing. The developments on the resistance of microorganisms to industrial antiseptics and disinfectants, their resistant mechanisms and the control strategies are reviewed, which aids us to reasonably use industrial organic antiseptics and disinfectants in existence and provides academic and scientific basis.

As an important part of traditional Chinese medicine (TCM), mineral medicine plays an irreplaceable role. However, little has been reported on its species and valence state of heavy metals and deleterious elements, and also the relevance to pharmacological effect and toxicology. The present paper, in a new perspective, summarized the determination of the species and valence state of heavy metals and deleterious elements in recent years, discussed the progress of the pharmacological effect and toxicology, and prospected for future study which might provide reference for mineral medicine.

Objective To further investigated the effect of minocycline on the inhibition of microglial activation and subsequent protection of nigral DA neuron.Methods 20 rats injected with LPS in the substantia nigra (SN) were randomly divided into two groups (LPS group and LPS+Minocycline group).The behavior was observed on the 7~(th) d and 14~(th) d.The immunohistoehemistry,in situ hybridization and Western-blot were used to detect the levels of positive neuron,mRNA,protein of TH and OX-42. Results The slightly rotational behavior was observed in LPS+Minoeyeline group.The majority of mieroglias were activated in the two groups.Some microglia in the SNpc remained ramified in LPS+ Minocycline group.The numbers of hypertophie microglia in LPS+Minoeyeline group were less than that in LPS group.Western-blot showed that the protein of OX-42 in two LPS groups was higher than in normal group(P

Objective To detect the expressions of CD19 and CD20 of B-lymphocytes (CD19+B, CD20+B) and natural killer (NK) cells in the peripheral blood of epileptic children and explore their significances. Methods Four hundred and fifty-eight epileptic children, admitted to our hospital from January 2008 to December 2010, were chosen as patient group; another 52 healthy subjects were chosen as controls. The expressions of CD19+B and CD20+B and NK cells were detected by flow cytometry; their results were compared. Ninety-two epileptic children were treated with intravenous immunoglobulin (IVIG) and the effect of IVIG therapy was studied. Results The CD19+B level ([22.35±6.54]％) and CD20+B level ([21.50±8.41]％) in the epileptic children were obviously higher than those in the healthy controls ([16.86±4.02)％,[16.13±4.19]％, P＜0.05); and the level of NK cells ([9.1 1±4.90]％) in the epileptic children was significantly decreased as compared with that in the healthy controls ([14.72±4.15]％, P＜0.05). The CD19+B level ([18.26±5.03]％) and CD20+B level ([16.74±5.12]％) 6months after MG treatment were decreased significantly as compared with those before treatment ([22.74±6.25]％,[21.61±8.03]％, P＜0.05]; while the level of NK cells ([14.65±4.58]％) 6 months after IVIG treatment was increased significantly as compared with that before treatment ([9.07±4.76]％,P＜0.05). Among the 92 patients treated with IVIG, 70 enjoyed good results and 22 had non-effective resutls; The changesofCD19+Blevel ([7.99±5.34]％) and CD20+B ([8.21±5.21]％) before and after treatment in effectively treated patients by IVIG were significantly different as compared with those in ineffectively treated patients by MG ([3.78±2.76]％,[3.66±2.48]％, P＜0.05); however, the changes of level of NK cells before and after treatment showed no significant difference between effectively treated patients and ineffectively treated patients ([5.28±4.55]％,[4.53％±4.43]％, P＞0.05). Conclusion Dysfunctions of B-lymphocytes and NK cells exist in epileptic children, and MG treatment shows good effect on immune dysfunction of them. The levels of CD19-B and CD20-B can be used as monitoring indicators in the IVIG treatment of epileptic children.

Objective To investigate the cognitive, intelligent and cranial MRI status of 4 patients with myotonic dystrophy type 1 (DM1). Methods A pedigree of 4 patients,admitted to our hospital from September 2011 to December 2011 and diagnosed as having DM1, were chosen in our study; Chinese edition tests of Wechsler adult intelligence scale and Wechsler memory scale were used to test the intelligence of these patients; Montreal cognitive assessment (MoCA) and Neurobehavioral cognitive status examination (NCSE) were applied to evaluate the patients' cognitive function.All of the 4 patients received a cranial MRI scan. Results Except for 1 patient,the other 3 patients had low intelligent quotient (IQ) and memory quotient (MQ),and their verbal IQs were all lower than performance IQs.Three patients showed impaired visual space/executive skills,calculation,memory,and conceptual thinking abilities; 1 patient showed impaired sentence repetition and verbal fluency on MoCA,though his final scores were within normal range. Three patients had brain atrophy to some extent on MRI scan,prominently in the frontal lobe and temporal lobe; white matter lesions and thickened skull were founded in all 4 patients. Conclusion Multiple cognition disorders and brain involvements can be found in DM1 patients and deserve further investigation.
