METHODS60 CMV-DNA positive and 40 CMV-DNA negative neonatal newborn from The Second Affiliated Hospital of Wenzhou Medical University and The first people's Hospital of Yongkang were screened, the blood biochemistry was analyzed, and the umbilical cord blood was reserved to detect the Connexin26 gene expression of mRNA with RT-PCR.PCR results was sequenced to track the newborn hearing, and analyze the correlations between neonatal cytomegalovirus types, the mutation of Connexin26 gene and hearing test results.RESULTS 26 cases from 60 CMV-DNA positive newborns were found with blood biochemical abnormalities. In all of the newborns, a total of 41 cases had 235delC mutation, 11 cases in the mutations for the development of hearing impairment. The results of correlation analysis showed that there were correlations between cytomegalovirus infection, gene mutation and hearing impairment.CONCLUSION Cytomegalovirus infection in neonates can lead to mutations in the Connexin26 gene, and may further lead to hearing impairment, and the probability of the mutation of Connexin26 gene and sensorineural hearing loss were higher in symptomatic cytomegalovirus infection neonates.

Objective To study the dynamic change of polysaccharide from Asarum insigne in Guizhou during different harvest period and its hemostatic effect. Methods Asarum insigne polysaccharide was extracted by water isolation and alcohol precipitation. We measured the polysaccharide content by UV spectrophotometry after impurity and purification and detected the bleeding and clotting time by tail cutting and slide methods in mice. Results There was significant variation in polysaccharide content of Asarum insigne at different harvest time, which was at a higher level in June(1. 78%-1. 82%). The bleeding time in mice of normal control group was (6. 73±1. 21) min,and that in mice treated with refined polysaccharide at high dose was (4. 91±1. 58) min,the difference between two groups was statistically significant(P<0. 01). The clotting time in mice of normal control group was (7. 27±2. 09) min,and that in the refined polysaccharide at middle and high dose groups was (3. 96±1. 78) min and (3. 27±1. 61) min,respectively. The latter two groups were obviously different from the normal control group(P<0. 05 or P<0. 01). Conclusion The polysaccharide is an active hemostatic substance in Asarum insigne and the optimum harvest time of it is in June for the clinical use.

Objective To evaluate the procedure of diagnosis and treatment for cystitis glandularis in female. Methods Forty-seven patients were classified into 3 groups randomly after being operated by tuansurethral resection:15 cases without any other therapy(A group), 16 cases with bladder instillation of pirarubicin afterward (B group), 16 cases with bladder instillation of mitomycin afterward (C group). Symptomatic reliof and recurrence were investigated in 1-year follow-up visit. Results Forty-four cases had fulfilled the entire follow-up visit. The effective rates of the three groups were 38.5%,87.5% and 86.7% respectively (X2=13.80,P＜0.01 ), the recurrence rate was 30.8% ,0,13.3% respectively (X2=4.86,P＞0.05).Conclusions The clinical situation of cystitis glandularis has no specificity. Cystisis glandularis has diversification of the clinical symptoms, urodynamics. Transurethral resection with bladder instillation is more effective than transttrethral resection simply, the recurrence rate is lower.

Objective:To study the psychosocial effect of fluorosis on students with dental fluorosis.Methods:115 students with different types of fluorosis were sampled randomly from fluorosis epidemic area of Xingtai city in Hebei province, including 60 of 12-year-old and 55 of 15-year-old students. Dental fluorosis was classified by Dean's Index (DI). Parents and teachers of the selected students were involved in a psychosocial questionnaire investigation which included five five-point questions, respectively.Results:Prevalence of fluorosis was 89.6% in the young students in the area. Evaluation scores by parents, which included “health of teeth”, “satisfaction of teeth” and “perceived well-being”, decreased with the decline of DI. Statistical difference was found in the answer to the five questions by parents when comparing the evaluation scores of control(without dental fluorosis) group,moderate dental fluorosis group and severe dental fluorosis group(P0.05). Difference of the evaluation scores of parents and teachers on boys and girls was not significant.Conclusion:Fluorosis has psychosocial impact on students, especially evaluated by parents.
