Objective To explore the liver pathology from live related liver transplatation(LRLT) of Wilson′s disease(WD) in children,and evaluatethe indication of LRLT.Methods The sample of this study,including the donater and patient,came from the LRLT. It was observed with HE,MASSON,Timm′s and Rubeanic staining.Results With HE and MASSON stainning,hepatocyte showed degeneration,fiber hyperplasic and false lobule formed;Timm′s and Rubeanic stainning showed typical black deposit of granules and conglomerations.Liver pathology revealed that liver cirrhosis appeared,and it was diffrentent from Child Pugh.Conclusions It is of great significance that the liver pathology is useful for the treatment of WD.If liver pathology supportes,the indication of LRLT can be measurably broadened.

AIM:To evaluate the feasibility and significance of nasal endoscope combined with Neodymium-doped Yttrium Aluminium Garnet ( Nd:YAG ) laser in the treatment of recurrent dacryocystitis.
METHODS: Forty-eight cases (48 eyes) with recurrent dacryocystitis were treated by nasal endoscope combined with Nd:YAG laser. The tubes were kept in place for 3-6mo after operation. The follow-up time was 3-18mo.RESULTS: Symptoms was completely resolved in 46 eyes and improved in 2 eyes, the cure rate was 100%. There were no other complications.
CONCLUSION: Nasal endoscope combined with Nd:YAG laser provides an ideal therapeutic for recurrent dacryocystitis because of its many advantages such as a few complications, simple operation, no scars on face and so on and is fit for clinical application in primary hospitals.

Objective To assess the effectiveness of prevention program on iodine deficiency disorders and iodine nutritional status of residents in Guangdong Province.Methods Probability proportionate to size sampling(PPS) was employed in surveillance of iodine deficiency disorders.Thirty counties(cities,districts) were selected in Guangdong Province.In each county(city,district) one township(street) was selected; in each township (street) one primary school was selected and in each primary school 40 children aged 8-10 were chosen to examine their thyroid and to collect salt samples at their home for determination of salt iodine.Out of the 40 children,12 children were chosen to collect urine samples for determination of urinary iodine.From the primary schools chosen,40 grade 5 students were selected for intelligence quotient(IQ) test.In the nearby of the primary schools,3 townships(towns,street) were selected and in each township(town,street) 5 pregnant and 5 lactating women were selected to collect their urine samples for determination of urinary iodine.Type-B ultrasonic was used in measuring the thyroid volume.The iodine content of urine samples was measured by the method of arsenic and cerium catalysis spectrophotometry.The iodine content of salt was determined quantitatively with the titration method.IQ was tested by Chinese combined Raven's test.According to geographical location and the implementation of iodized salt,the effects of iodized salt on iodine deficiency disorders were analyzed in the plains and the Pearl River Delta Coastal region with mild iodine deficiency(iodized salt implementation region,referred to as the plains and the PRD),historical iodine deficiency areas (iodized implementation region) and the eastern and the western coastal areas of Guangdong(areas with non-iodized salt problem,referred to as the eastern and the western Guangdong).Results A total of 1200 children aged 8 to 10 were examined by type-B ultrasonic test,and goiter rate was 3.5％ (42/1200).The differences of goiter rate between the plains and the PRD,the historical iodine deficiency areas and the eastern and the western Guangdong were statistically significant (x2 =6.6,P ＜ 0.05).The goiter rate (6.1％) in the eastern and the western Guangdong was significantly higher than that of the plains and the PRD and the historical iodine deficiency areas (3.3％,2.0％,x2 =5.6,7.1,all P ＜ 0.05).A total of 1200 salt samples were examined.The median and coefficient of variation of iodine in the salt were 31.0 mg/kg and 23.2％,respectively.Coverage of iodized salt was 97.5％(1170/1200) while 96.1％(1153/1200) of consumed iodized salt was qualified.The median urinary iodine of 1200 children aged 8-10 was 186.5 μg/L,and the differences of median urinary iodine between the plains and the PRD,the historical iodine deficiency areas and the eastern and the western Guangdong were statistically significant(x2 =5.9,P ＜ 0.05).The median urinary iodine of the eastern and the western Guangdong(162.4 μg/L) was significantly lower than that of the plains and the PRD(207.5 μg/L,x2 =8.7,P ＜ 0.01).The difference of median urinary iodine between the plains and the PRD,the historical iodine deficiency areas and the eastern and the western Guangdong was statistically significant(x2 =58.9,P＜ 0.01).The median urinary iodine of the eastern and the western Guangdong(109.6 μg/L) was significantly lower than that of the historical iodine deficiency areas and the plains and the PRD(152.9,155.2 μg/L,x2 =18.3,20.6,all P ＜ 0.05).The mean IQ of the 1208 grade 5 students was 102.8 ± 14.3.The IQ of the plains and the PRD(104.3 ± 13.9) and the historical iodine deficiency areas(102.7 ± 14.3) was significantly higher than that of the eastern and the western Guangdong(100.3 ± 14.7,t =3.8,2.1,P＜ 0.01 orP＜ 0.05).Conclusions The goal of iodine deficiency disorders elimination is achieved as scheduled in Guangdong Province.The health level of general population has been improved significantly.Iodine nutrition is in the appropriate range (100-199 μg/L) in general population but low in pregnant women.The selling of non-iodized salt in the eastern and the western Guangdong Province should be followed closely.

Education reform and innovative education are the strong requirements of the times and social development.We developed immunological paper free examination system based on the optimized question bank,characteristics of immunological examination and information technology.This system can randomly develop electronic examination paper and can integrate the processes of exam registration,examination paper development,online examination,paper inspection,scores generation and printing into one system,which can save human resources,enhance the accuracy and fairness of the examination,making it conform to international standards.

Objective:To investigate the effect of miR-150 gene deletion on the breeding and hematologic parameters of mice. Methods:The nest litter size,wean rate and weight changes of miR-150 knock out (miR-150ko) and C57BL/6J mice were com-pared. The hematology indexes were analyzed by automated blood cell counter, the serum biochemical parameters were analyzed by automatic biochemical analyzer. Results:The nest litter size and wean rate of miR-150ko mice were significantly decreased compared with that of C57BL/6J mice. The number of total white blood cells,intermediate cells,neutrophils,and the percentage of neutrophils and intermediate cells were significantly increased in miR-150ko mice compared with that of C57BL/6J mice. However,the number and per-centage of platelets and lymphocytes decreased significantly in miR-150ko mice. In addition,the levels of serum glucose and TC were in-creased significantly in miR-150ko mice compared with that of C57BL/6J mice. Conclusion: miR-150 gene deletion impairs the breeding and has complex impact on hematologic parameters of mice.

Objectives:To understand the current situation of premenstrual syndrome (PMS) and type D personality in female college students,and to explore the relationship between them.Methods:Totally 856 female college students were assessed with the Premenstrual Syndrome Scale (PMSS,those with total score of 6 or higher as having PMS) and Type D Personality Scale 14 (DS-14,those negative emotion and social inhibition factor with total score of 10 or higher as having type D personality).Result:A total of 280 students were detected with PMS,and the rote was 32.7％.Totally 272 students were detected with the type D personality,and the rote was 31.8％.The total score of DS-14 and the score of 2 factors were higher in PMS group than in non-PMS group (Ps ＜0.001).The rate of PMS was lower in type D personality group than in non-type D personality group (11.76％ vs.25.34％,P ＜ 0.001).Conclusions:The occurrence of premenstrual syndrome may be related to the type D personality.The evaluation of personality characteristics should be taken into consideration when formulating the intervention program.
