To research the association between primary progressive pterygium and tear film.
●METHODS: Totally 60 cases of primary progressive pterygium from September 2012 to June 2013 in our hospital were enrolled. The pterygium eye was for observation group and the contralateral eye as the control group. The differences of eye symptoms, tear film break-up time ( BUT ), Schirmer Ⅰ test ( S Ⅰ t ), corneal fluorescein staining (FL), tear ferning test (TFT) and the conjunctival impression cytology ( ClC) were compared between two groups.
●RESULTS: The eyes in observation group had higher symptoms score, FL score, grades of conjunctival squamous metaplasia, percentage of abnormal tear ferning, but had lower BUT and density of goblet cell, the differences had statistically significance (P<0. 05); Similar S Ⅰ t results were presented in the two groups, the difference had no statistically significance (P>0. 05).
● CONCLUSlON: Primary progressive pterygium can cause a decrease in tear film stability, which in turn lead to some dry eye symptoms such as dry feeling and burning sensation, and its mechanism may be caused by multi-factors, such as density change of goblet cell and the tear fluid dynamics.

Objective To explore the clinicopathological characteristics of non-muscle-invasive bladder cancer patients association with chronic kidney disease (CKD).Methods Between Jan 2009 and Dec 2010,536 patients (390 males and 146 females with mean age of 63 years) underwent surgical treatment at our institute for pathologically proven non-muscle-invasive bladder cancer.The clinical and pathological data of these patients were reviewed,and the relationships of these factors and CKD were analyzed.Presence of CKD was confirmed in patients with estimated glomerular filtration rate (eGFR)＜ 60ml/(min · 1.73 m2)calculated using the Modification of Diet in Renal Disease Study equation.Results Of the 536 consecutive cases,57 patients (10.6％) had CKD.Compared to the patients without CKD,there were more females and older patients in the patients with CKD (52.6％ vs 24.2％ and 69 years vs 62 years,both P ＜ 0.05).The patients with CKD proned to have multiple bladder tumor (71.9％ vs 50.9％,P ＜ 0.05) and synchronous upper urinary tract urothelial carcinoma (7.0％ vs 2.3％,P ＜0.05).The history of bladder cancer and upper urinary tract urothelial carcinoma were also predominated in these patients (43.9％ vs 29.0％ and 40.4％ vs 6.5％,both P ＜ 0.05).ConclusionConcurrent CKD in non-muscle-invasive bladder cancer patients is associated with greater risk of multiple tumors in urinary tract,particularly in female patients.

Objective To understand the prevalence of anemia and its influencing factors in infants aged 6 to 24 months in poor areas of Gansu Province, and to provide reference for improving the prevalence of anemia in local children. Methods A multi-stage sampling method was used to conduct a survey on infant and caregivers, in the 12 children nutrition improvement project counties in Gansu Province. T-test and analysis of variance were used to compare the hemoglobin content, the chi-square test was used to compare the prevalence of anemia, and the Logistic regression model was used to analyze the influencing factors. Results Among the 3 188 effective data, the detection rate of anemia was 25.69% (819). The detection rate of anemia among boys and girls was 24.54% and 26.90%, respectively. There was no significant difference in the detection rate of anemia among different sexes ( 2=2.326, P=0.127). The detection rate of anemia between different age groups were statistically significant ( 2=42.339, P<0.001); The results of multivariate analysis showed that children's age, children's ethnic groups, parents' awareness of feeding knowledge, the feeding method of 6 months after birth and the way of taking nutritional packs were associated with anemia (all P<0.05). Conclusions The prevalence of anemia in infants aged 6 to 24 months in poor areas in Gansu Province was relatively high. Strengthening the education of caretakers’ knowledge of guardian feeding and scientific child-rearing, and ensuring the nutrition packages intake can significantly reduce the prevalence of anemia prevalence in poor areas in Gansu Province.
