OBJECTIVE:
To explore the relationship of the expression of thymic stromal lymphopoietin (TSLP) in nasal polyps tissues and the Th2 inflammatory response.
METHOD:
Sixty patients with nasal polyps were collect ed. The immunohistochemical staining method was used to detect the expression of TSLP in nasal polyps tissues and ELISA method to the expression of IL-4, IL-5, IFN-gamma, IL-13 and analyzed the correlation between them.
RESULT:
The expression of TSLP in nasal polyp tissues was higher than that in normal inferior turbinate mucosa (P < 0.05). The expression level of IL-4, IL-5, IFN-gamma and IL-13 in nasal polyps tissues were significantly higher than those in control group (P < 0.05). TSLP staining was a statistically significant positive correlation with IL-4, IL5 and IL-13 (r = 0.475, 0.594 and 0.582, respectively, P < 0.01), while inverse correlation with IFN-gamma (r = -0.614, P < 0.01).
CONCLUSION
The high expression of TSLP might promote T cell differentiation towards Th2, and participated in the occurrence/development of nasal polyps, aggravated the nose Th2 inflammatory response.

Background Blepharitis is a common ocular surface disease.It is associated with the disorder of lipid secretion of meibomian gland.The change of tear film stability can cause dry eye symptoms,so blepharitis is thought to be one of the factors causing dry eye,but the relation between them is in study. Objective This study was to observe the morphology of meibomian gland in blepharitis patients and to investigate the correlation of morphology of meibomian gland with dry eye. Methods A series of case-observational study was designed in this study.A total of 83 eyes of consecutive 83 blepharitis patients were enrolled in Henan Eye Institute from October 2010 to April 2011.Blepharitis was diagnosed based on American Preferred Practice Pattern Guidelines.Some relevant ocular examinations were performed under the informed consent of the subjects,including the anterior segment manifestation by the slit lamp,such as meibography,lid margin abnormality,and the dry eye-relevant examinations,such as tear film break-up time (BUT),Schirmer test Ⅰ and corneal fluorescein staining also been carried out.Tear film shape was examined by film interference images and scored.Absent degree of meibomian gland was graded under a Noncontact Infrared Meibography.The correlations of absent degree of meibomian gland with ocular syndrome score,dry eye examination results were evaluated using Spearman rank correlation coefficients.Informed consent was obtained prior to this trail. Results No significant difference in the frequencies of blepharitis was found between male and female among different ages (x2 =2.69,P =0.75 ).Absent grading of the meibomian glands was positively correlated with age of blepharitis patients ( r =0.58,P =0.00 ),lid margin abnormality scores ( r =0.64,P =0.00 ),conjuntival hyperemia score ( r=0.50,P =0.00),tear film interference imaging grade ( r =0.23,P =0.04 ),corneal fluorescein staining score( r =0.50,P =0.00 ) but was negatively correlated with BUT ( r =-0.32,P =0.00 ).No significant correlation was found between meibography grading and gender( r =-0.09 ; P =0.99 ) or Schirmer test Ⅰ ( r =-0.05;P =0.69 ).No significant difference was found in meibography grading between male and female in different age groups(Z=-0.09,P=0.93). Conclusions Blepharitis can irriter dry eye symptom because of overevaporation of tear fluid and abnormality of secreting function of meibomian glands.The missing of the meibomain glands increases with age in the patients with blepharitis.Noncontact Meibography System is an assistant tool to the diagnosis of blepharitis.

Objective To observe the renal lesion caused by aristolochia manshuriensis kom(AMK) through 2 infants who had used AMK before hospitalization.Method Retrospecting the 2 cases of infants caused by AMK from 2002 to 2003,and evaluating their pathogenesis,treatment,and prognosis.Result Two infants both presented with symptoms of acute renal failure(ARF),and poor outcome.Conclusions Renal lesion in infant caused by AMK is serious.Some medcines,such as glucocorticosteroid,may be useful for its treatment and prognosis.

Objective To explore the pathogenesis and prognosis of acute renal insufficiency in children.Method The pathogensis,clinical manifestation,treatment and prognosis retrospected and discussed by analysis of the clinical features of 34 children with acute renal insufficiency hospitalized in 2002-2005.Results Of 34 children,there were 15 females and 19 males,the age range from 16 days to 15.5 years old.Among pathogenesis of acute renal insufficiency,primary glomerular diseases occupied 35.3% and drug-induced acute renal insufficiency occupied about 29.4%.The mortality of drug-induced acute renal insufficiency was 20% of and about 30%(deve-)loped chronic renal insufficiency was 30%.Conclusions Primary glomerular diseases rank the dominant causes of acute renal insufficiency,while drug-induced acute renal insufficiency has poor prognosis.So it is important to treat primary glomerular diseases in early stage and emphasize the side effect of drugs to kidney.
