AlM:To investigate the prevalence of pterygium of the household population aged 40 and above in Hengli Town of Dongguan.
METHODS: Using the method of cluster random sampling, select 3 628 people aged 40 and above in four villages and one community for visual examination, intraocular pressure check, slit lamp examination and questionnaire.
RESULTS: The actual number of subjects was 3 393 people, and examination rate was 93. 52%. We detected 843 patients with pterygium. The prevalence of pterygium was 24. 85%.
CONCLUSlON:There is high prevalence of pterygium in Dongguan area. The prevalence of pterygium is related with age and working environment, but has no relation with gender.

Objective To investigate expression levels of epithelial mucin 1 (MUC1) and epitbelial mucin15(MUC15) in elderly patients with papillary thyroid carcinoma and assess the role of MUC1 and MUC15 in the pathogenesis of thyroid papillary carcinoma.Methods Protein expression of MUC1 and MUC15 was detected by immunohistochemistry in 10 samples from normal thyroid tissue adjacent to thyroid adenoma,57 samples from papillary thyroid carcinoma (PTC),and 14 samples from PTC in neck lymph node metastasis.Results Expression rates of MUC1 in normal thyroid tissues,thyroid papillary carcinoma,and lymph node metastatic carcinoma were 40.0％,75.4％,64.3,respectively,and the rates for MUC15 were 0,73.7％,71.4％,respectively.The positive expression rate of MUC1 was higher in PTC tissues than in normal thyroid tissues (x2 =5.10,P=0.02) and,compared with normal thyroid tissues,the positive expression rate of MUC15 increased in PTC tissues and lymph node metastatic carcinoma (x2 =12.25 and 19.75,both P＜0.05)MUC15 protein expression was higher in micro-PTC (less than or equal to 1 cm in diameter) than in carcinoma larger than 1 cm in diameter (90.9％ vs.62.9,x2 =5.48,P=0.02).MUC15 expression was higher in PTC without lymph node metastasis than in PTC with lymph node metastasis (83.8％vs.55.0％,x2 =5.55,P=0.02).MUC1 expression was positively correlated with MUC15 expression in thyroid papillary carcinoma (r=0.35,P=0.01).Conclusions MUC1 and MUC15 may have synergistic effects in the initiation and progression of PTC.MUC15 may play a role in regulating tumorigenesis of thyroid papillary carcinoma in early stages and can potentially serve as a supplementary marker in the screening of micro-thyroid papillary carcinoma.

Objective To compare the detection efficiency between multiplex RT-PCR method and liquichip technology for screening the viral etiological agents of diarrhea.Methods The development of the multiplex RT-PCR method.A total of 107 feces samples from patients who suffered from diarrhea and attended to Zhujiang Hospital of Southern University from September 2013 to February 2014 were collected and tested in parallel by both multiplex RT-PCR and xTAG Gastrointestinal Pathogen Panel ( xTAG GPP) for Adenovirus, Norovirus genogroupⅠandⅡ, as well as by both multiplex RT-PCR and monoplex RT-PCR for Astrovirus and Sapovirus.To evaluate the sensitivity and specificity of multiplex RT-PCR, xTAG GPP and monoplex RT-PCR were used as reference.Kappa coefficient test was used to evaluate the consistency among the methods.The detection limit and accuracy of multiplex RT-PCR were evaluated by detection of serial dilution of positive plasmids and products sequencing for the five viral agents.Results The multiplex RT-PCR showed high consistency with xTAG GPP and monoplex RT-PCR, in which Kappa value was 0.885 and 1.000 respectively( P=0.000 ).Compared to xTAG GPP, the sensitivity and specificity of the multiplex RT-PCR were at average of 80.8%( 21/26 ) and 100%( 295/295 ) respectively.The detection limit and accuracy of multiplex RT-PCR were 104 copies /μl-106 copies/μl.Conclusion The high consistency indicated that both the multiplex RT-PCR and xTAG GPP are useful as a special,sensitive, high throughput and rapid diagnostic tools for the detection of the major viral pathogens related to diarrhea in clinical laboratory.

Objective To study the main pharmacodynamics effect of compound lavender ointment on the scald, anti-inflammation and analgesia.Methods Sixty guinea pigs were divided into normal groups,model groups( superficialⅡ°scalding models) ,compound lavender ointment high,median,low dose groups,and jing wan hong ointment groups,then observation of the wounds and healing was made and recorded.Histopathological examination was made to examine the wounds,and ELISA to analyze serum TNF-α、IL-6、IL-8.Xylene ear swelling model and writhing test were used to observe the analgesic and anti-inflammatory effects of the compound lavender ointment.Results Compound lavender ointment can relieve the wounds swelling and exudation,which may be related to the decrease of proinflammatory cytokines(P <0.01), and promote the wound healing significantly( P <0.01) ,that the side-effects were not observed.High dose of compound lavender ointment can inhibit ear swelling and have certain analgesia with the writhing tests.Conclusion Compound lavender ointment have the promoting wound healing,anti-infectious and antalgic effects on the scald.
