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.

In order to characterize the molecular epidemiology of HFMD-associated Coxsackievirus A6 (CVA6) in Fujian Province, a total of 1340 specimens from non-EV71 non-CVA16 HFMD patients were collected during 2011-2013. Isolated virus strains were identified and subtyped. Full-length coding regions for the VP1 gene of the predominant serotype CVA6 isolates were amplified and sequenced. Among the 375 non-EV71 non-CVA16 HFMD cases confirmed by virus isolation and molecular subtyping, 182 (48.5%) were found to be caused by CVA6, accounting for 7.9%, 16.2% and 39.6% HFMD-associated enteroviruses in FujianProvince during 2011, 2012, and 2013, respectively. Compared with general features observed in the HFMD epidemic, no difference in CVA6-specificity or severity rates was observed between geographical origins, gender, or age groups. Nucleotide sequence analyses of VP1 genes revealed high diversity levels of 16.2%-18.6% among CVA6 strains from Fujian Province, in contrast to the prototype CVA6 strain, and showed low levels of diversity in the amino acid sequences (4.3%-6.2%). Phylogenetic analysis also indicated that CVA6 isolates from Fujian Province were distinct from the prototype strain and other isolates from abroad; however, it was homologous to domestic strains, although the Fujian isolates clustered into multiple branches. These results suggested that significant changes in the pathogenic spectrum of HFMD in Fujian Province occurred during 2011-2013, as CVA6 was one of the predominant serotypes of HFMD. CVA6 isolates from Fujian Province were co-circulating and co-evolving with other domestic strains as multiple closely related CVA6 transmission chains were observed in Fujian Province overall and within each prefecture.

To look for the toxicity fraction of Euphorbia pekinensis and discuss the vinegar processing mechanism. The level of intestinal edema, water content of intestine and stool, IC50 values of IEC-6 were applied to evaluate the toxicity of different fractions. RT-PCR was employed for detecting AQP1, AQP3 mRNA expression. The petroleum ether (PE) fraction and ethyl acetate (EtOAc) fraction could significant cause intestinal edema in mice, increase the water content of duodenum, colon and stool, inhibited the mRNA expression of AQP1 and increased the mRNA level of AQP3 in colon, and the petroleum ether (PE) fraction was more poisonous. After the petroleum ether (PE) fraction was processed with vinegar, the level of intestinal edema, water content of duodenum, colon, stool and inhibition ratio of cells line were reduced. And we compared the composition change after vinegar processing, finding that the conpekinensis.

OBJECTIVETo study the epidemiologic characteristics of hand-foot-mouth disease (HFMD) in Guiyang between 2008 and 2010.

METHODSThe epidemiologic characteristics of HFMD were analyzed by descriptive statistical methods based on the data from the China Information System for Disease Control and Prevention.

RESULTSA total of 27383 cases of HFMD were recorded in Guiyang between 2008 and 2010. The incidence of HFMD increased from 66.4439/100000 in 2008 to 163.9276/100000 in 2009 and 471.5515/100000 in 2010 (P<0.01). The mortality rate was 0.1026/100000 in 2010, which was significantly lower than in 2009 (0.2821/100000) (P<0.05). HFMD occurrence showed seasonality and reached a peak between April and June. HFMD cases were commonly noted in children under 5 years old, and especially in children under 3 years old. The main detected pathogen was human enterovirus 71 (EV17) in 2009. Whereas in 2010 the disease was mainly caused by CoxA16 and other intestinal viruses.

CONCLUSIONSThe incidence of HFMD in Guiyang increased year by year from 2008 to 2010, but the mortality rate decreased year by year. HFMD occurrence showed an obvious seasonality. HFMD was common in children under the age of five. The main pathogens of this disease included EV17, CoxA16 and other intestinal viruses.
