Objective To explore the effect of oxytocin on uterine fibroids treated by ultrasound ablation. Methods Eighty-two single points in 29 uterine fibroids from 26 patients were sonicated with magnetic resonance imaging guided by high intensity focused ultrasound before and after using oxytocin. The required total energy, sonication time required to reach 60 ℃ and the acoustic energy for increasing 1 ℃ of temperature at the single point before and after using oxytocin were compared. Results Before intravenous infusion of oxytocin, the average total sonication energy required to reach 60 ℃ was (5320 ±910) J and it took (21 ±20) seconds for sonicating a single point, the energy required for increasing 1 ℃ was (255 ± 302) J. In contrast, after intravenous infusion of oxytocin, the average total sonication energy required to reach 60 ℃ was (2890 ±325) J, and it took (12 ±7) seconds for sonicating a single point, the energy required for increasing 1 ℃ was ( 126 ± 94 ) J. Those three index all reached statistical difference ( P = 0.002, P = 0.001, P= 0.002, respectively). Conclusion It seemed that Oxytocin could significantly decrease the energy required for ablating uterine fibroids, shorten treatment time and improve the treatment efficiency.

BackgroundIt has been proved that,after being forced,the biological soft tissue has stable biomechanical characteristics.However,there is rare study on corneal biomechanics.Rabbit is a main animal for experimental study in ophthalmology.But the biomechanical study of cornea in normal rabbit has not been reported.ObjectiveThis study was to investigate the biomechanical properties of normal rabbit central cornea and acquire the parameter. Methods Ten rabbits were sacrificed and the whole corneas were obtained and 20 central cornea specimens with 7 mm×5 mm of rabbit were prepared and tested on BOSE electroforce 3220-AT biomechanics machine under the room temperature and suitable humidity environment.Uniaxial tension,stress between strain,relaxation and creep were performed and the curves were drawn.The data was collected by wintest system to evaluate the biomechanical parameters of rabbit corneal tissue. ResultsThe maximum distortion intension of rabbit cornea was (7.7432±0.6099)MPa.After three cyclic loading,the stress gradually attenuated and the stress and strain flattened as the time change with the relaxation rate 30.33%.The deformation of the specimens enhanced with time decrease with the creep rate 24.33%. ConclusionsThe biomechanical characteristics of normal rabbit cornea are revealed in this study,which offer the basis for the experimental research of rabbit model aimed at corneal disease.

Objective To identify changes in the occurrence of endemic fluorosis in order to provide scientific basis for making countermeasures. Methods Five villages from 14 counties of mild, moderate and severe fluorosis affected areas were selected by stratified cluster sampling every year in the whole province during 2006 - 2010. Water and urinary fluorine were determined by ion selective electrode method(GB/T 8538-1995); dental fluorosis of children 8-12 years old was diagnosed with Dean method; skeletal fluorosis was diagnosed according to "clinical indexing standards of endemic skeletal fluorosis "(GB 16396-1996), between 2006 and 2008, and "clinical diagnosis standard of endemic skeletal fluorosis"(WS 192-2008) between 2009 and 2010. Results A total of 25 diseased villages were surveyed, 14 with water sources changed, covered a resident population of 8005 people, beneficiary population 7154, and accounting for 89.37% of the resident population; not changed villages 11. In accordance with the "State drinking water health standards", in the 14 changed villages the fluoride in drinking water was qualified (≤ 1.20 mg/L), there were 3 schools whose water fluorine content exceeded the standard; among the 11 villages that did not change water sources 7 drinking water samples fluorine content exceeded the standard. Of the 8 to 12 years old children in villages with changed water sources, 363 of them were checked and 142 dental fluorosis were found, the detection rate of dental fluorosis was 39.12% (142/363); in villages with water sources not changed, 303 children were checked, the detection rate of dental fluorosis was 43.89%(133/303). Of sixteen and elder adults in water source changed villages, 6424 people were checked and 403 skeletal fluorosis were found, skeletal fluorosis detection rate was 6.27% (403/6424); 3572 people were checked in not changed villages, the detection rate of skeletal fluorosis was 13.89%(496/3572). In water sources changed areas, geometric mean of urinary fluoride was in the normal reference value(WS/T 256-2005, 1.40 mg/L)or less. Conclusions Endemic fluorosis is decreased in water improved areas, but in unimproved areas the disease is still severe, and control of endemic fluorosis is still an arduous task.

OBJECTIVETo explore the prevalence of syphilis and risk factors on pregnant women in Fujian province.
METHODSFrom July 1st, 2004 to June 30th, 2006, epidemiologic methods as questionnaires to fill in and rapid plasma reagent testing (RPR) were performed. Pregnant women with positive RPR test and then were confirmed by treponema pallidum test (TP). Intervention was provided to the pregnant women who were followed up to the postpartum periods. Results were compared during the peri-neonatal stage between syphilis-infected and non-infected women. Factors which were relative to syphilis infection were analyzed by simple and then further logistic regression analysis.
RESULTSThere were 38 418 pregnant women under study, of whom 772 were confirmed including 60 who were still pregnant. The prevalence of syphilis during pregnancy was 1.85% (712/38 418), with mostly underlying syphilis which played an important role during the neonatal stage. Main risk factors to have been found as: women's occupation, cultural background, place of living, husband's occupation, family income, having sexually transmitted disease(STD) infection. The prognosis of peri-neonatal stage was worse if the mother was having blood RPR test positive. Mortality of peri-neonatal, preterm birth rate and low-birth weight rate were found also higher among mothers when RPR was positive (P < 0.01).
CONCLUSIONThe prevalence of syphilis in Fujian province was going up yearly. 8 factors including women's occupation, cultural background, place of living, received poor health education, having multiple sexual partners, husband's occupation, family income and having STD were main risk factors in the province, the mother's status of syphilis infection would strongly relate to the peri-neonatal stage of pregnancy.

Objective To explore the maternal-fetal transmission patterns and interventional methods of syphilis during pregnancy.Methods A total of 847 cases of syphilis in pregnancy confirmed by rapid plasma reagin test(RPR)and treponema pallidum hemoagglutination test(TPHA)were treated with procaine benzylpenieillin intramuscular injection,and with erythrocin oral medication if hypersensitive to benzylpenicillin.Eight hundred forty seven cases of syphilis during pregnancy were followed up for pregnancy outcomes.And their newborn babies were tested using the RPR.The newborns with positive results were given intervention and followed up until 24 months after birth.Results(1)A total of 733 cases among the total 847 have given birth to living-babies,in which 626 cases were tested using RPR,and the positive rate was 55.1%(345/626).(2)The RPR positive rate,neonatal mortality,preterm birth rate and low birth rate in the newborn of mothers with an RPR titer higher than or at 1:8 were higher than those of mothers with an RPR titer lower than 1:8(P
