Dental Epidemic Diseases and Oral Health Knowledge in People with Disabilities: a Survey in a Southwest City of China

PEOPLE with disabilities constitute an important group in the field of oral health care, yet have rarely been studied.Based on WHO methodol- ogy of oral health survey, data of 531 persons with disabilities in vision, hearing, intelligence or extremity, or with mental disease are collected from 4 different dis- Received for publication November 4, 2010.

Oral Epidemic Diseases of Exposure Personnel in Long-term Low Dose Radiation

ORAL epidemic diseases of exposure personnel in long-term low-dose radiation yet have rarely been studied.Referred to WHO oral health survey method and symptom grading standard,data of 341 exposure persons in long-term low-dose radiation including o particle,β particle,and y rays,etc.,were collected from one camp in China in 2011 with cluster sampling and analyzed with Foxpro 6.0 and SPSS 16.0software.

Effect of Th1/Th2 balance on serum prostaglandin,COX-2,AVP and OT in primary dysmenorrhea rats with cold coagulation and blood stasis syndrome

Objective:Explore the role of Th1/Th2 balance in the pathogenesis of primary dysmenorrhea through study the effect of Th1/Th2 balance drift on serum prostaglandin F_(2α),prostaglandin,6-keto-prostaglandin F_(1α),TXB2,COX-2,AVP and OT in Primary Dysmenorrhea Rats with cold coagulation and blood stasis syndrome.Method:The rat model of primary dysmenorrhea with cold coagulation and blood stasis syndrome was established.On the basis of this model,Th1 shift model and Th2 shift model were established.The rats were divided into blank group,model group,Th1 shifting group and Th2 shifting group.The writhing reaction of rats in each group was compared,and the contents of PGF_(2α),PGE_(2),6-keto-PGF_(1α),TXB2,COX-2,AVP and OT in serum were detected.Results:Writhing latency:There was no significant difference between Th1 and Th2 shifting groups(P>0.05),Th2 shifting group was shorter than Th1 shifting group(P<0.05).Writhing times in 30 minutes:Compared with the model group,the writhing times of Th1 shifting group decreased significantly(P<0.01),while Th2 shifting group increased significantly(P<0.01).Compared with the blank group,the contents of PGF_(2α),TXB2,COX-2,AVP and OT were increased(P<0.05,P<0.01),and the contents of 6-keto-PGF_(1α)and PGE_(2)were decreased(P<0.01).Compared with the model group,the contents of PGF_(2α),TXB2,COX-2 and AVP in Th1 shifting group were decreased(P<0.05,P<0.01),and the contents of 6-keto-PGF_(1α)and PGE_(2)were increased(P<0.01),while the contents of PGF_(2α),TXB2,COX-2,AVP and OT in Th2 shifting group were increased(P<0.01),and the contents of 6-keto-PGF_(1α)and PGE_(2)were decreased(P<0.01).Conclusion:The intervention of Th1/Th2 cell balance on the expression of PGF_(2α),PGE_(2),6-keto-PGF_(1α),TXB2,COX-2,AVP and OT may be one of the pathogenesis of PD with cold coagulation and blood stasis syndrome.
