Objective To investigate the prevalence of endemic fluorosis in Guide county of Qinghai province, in order to provide appropriate measures to monitor and control the disease. Methods Damo, Wenquan, Baoning villages(water source has been changed) and Taiping village(water source has not been changed) in Guide county were involved in the study in 2008. One tap water sample was collected in dry and rainy seasons, respectively. Water fluoride was tested in accordance with the "Standard Test Methods for Drinking Water" (GB/T 5750.5-2006); of all the children aged 8 to 12, dental fluorosis was diagnosed using Dean criteria; 6 copies of urine samples were collected in each age group, urinary fluoride was measured using fluoride ion-selective electrode (WS/T 89-1996). According to the "Clinical Diagnostic Criteria of Endemic Skeletal Fluorosis "(WS 192-2008), clinical skeletal fluorosis was determined in adults over the age of 16 by X-ray examination for 10 people in each selected village. Results The mean water fluoride was 0.58,0.38,2.28,0.37 mg/L in Damo, Wenquan, Taiping, and Baoning villages, respectively, and that of Taiping village exceeded the national standard(1.0 mg/L). One hundred and ninety-three children aged 8-12 were checked, the detection rate of dental fluorosis was 49.74% (96/193); urine samples of 116 children were tested, median urinary fluoride was 1.49 mg/L A total of 1503 adults over the age of 16 were examined, the clinical detection of skeletal fluorosis was 51.63%(776/1503); a total of 82 people were X-rayed, X-ray detection of skeletal fluorosis was 20.73%(17/82). The characteristic of X-rays were degeneration and ossification of interosseous membrane. Conclusions Prevalence of dental fluorosis of children and adult clinical skeletal fluorosis are higher. The endemic fluorosis is still comparatively serious. Prevention efforts need to be further strengthened.

Objective To investigate the impact of previous cystectomy for ovary benign cyst on ovarian reserve and pregnancy outcome in in vitro fertilization/intracytoplasmic sperm injection-embryo transfer (IVF/ICSI-ET) cycles. Methods Totally 622 infertility patients were retrospectively investigated who underwent first IVF/ICSI-ET cycle in Reproductive Hospital Affiliated to Shandong University from January 2013 to June 2014. There were 153 cases who had been removed ovarian cyst by cystectomy surgeries recruited as study group, in which 44 cases of ovarian endometriosis cyst, 35 cases of benign ovarian teratomas, 67 cases of simple ovarian cyst and 7 cases of ovarian mucinous cystadenoma. In contrast, 469 infertility patients with tubal-factor infertility or male factor were included as control group. The age-matched women in the control group had no ovarian surgery previously. The indicators of ovarian reserve and pregnancy outcome were analyzed between two groups. The influence of different types of ovarian cysts on ovarian reserve and pregnancy outcome in IVF/ICSI-ET cycles were also studied, ovarian endometriosis cyst was studied as Group A, and Group B consisted of benign ovarian teratomas, simple ovarian cyst and mucinous cystadenoma. Results (1) The significantly lower serum antimullerian hormone (AMH) level (median: 1.92 versus 2.90 mg/L), antral follicle count (AFC; median: 12.0 versus 13.0), retrieved oocytes (12 ± 5 versus 13 ± 6) and the number of embryo cryopreserved (median:1.0 versus 3.0) were found in study group compared with control group (all P<0.05). There was no statistical difference between two group for the following parameters, such as basal FSH level, the total dosage of gonadotropin duration and the total dosage of gonadotropin (all P>0.05). A better clinical pregnancy rate was achieved in control group (61.6%, 241/391) than that in study group (61.4%, 81/132), but no significant difference was existed (P=0.96). (2) Compared to Group B, Group A had fewer AFC, lower serum AMH level, retrieved oocytes and the number of embryo cryopreserved (11±4 versus 13±5;1.65 versus 2.15 mg/L;9±4 versus 13±5;0 versus 2.0;all P<0.01). There was a lower clinical pregnancy rate in Group A than that in Group B [50.0% (19/38) versus 66.0%(62/94)], accompanying with higher abortion rate [3/19 versus 9.7%(6/62)], but no differences were observed (all P>0.05). Conclusions Ovarian reserve declines after the cystectomy for ovarian benign cysts and the cystectomy has a negative impact on IVF/ICSI-ET cycle, resulting in a decrease of the number of retrieved oocytes and the number of embryo cryopreserved, but do not influence clinical pregnancy outcome. Ovarian reserve is impaired more seriously by cystectomy for ovarian endometriosis cyst than other ovarian benign cyst.

Objective To observe the state of endemic flurosis, construction and running status of water improvement projects in order to provide a scientific basis for prevention and treatment fluorosis. Methods Water samples of the diseased and nondiseased villeges were collected from east, west, south, north and centre of each villege in 2005, and fluoride concentration was determined for each surveyed village with unimproved-water. At the same time, all the tap water and source water samples were collected to determine fluoride concentration in each water-improved village surveyed. In 2008, all the endemic fluorosis villages in Guied county were divided into slight, medium and heavy types according to the water fluoride content before water improved, and 1,1,3 survey villages were chosen from each type. In all of the village children aged 8 to 12 years were tested for dental fluorosis by Dean method. Six copies of the urinary fluoride were sampled in different age groups. The fluorine content in water and urine was determined by F-ion selective electrode. The situation of clinical skeletal fluorosis of adults over 16 years of age was investigated, 20 adults (evenly divided between men and women) in the villages of medium and heavy types were examined by X-ray for skeletal fluorosis. Results In 3 village fluoride content of drinking water exceeded the national drinking water standards ( <1.0 mg/L) of 85 surveyed villages with improved-water. Among the 16 projects, 8 were intermittently running and 3 were retired, leaving only 31.25% of the projects active. Theprevalence of enamel fluorosis was 41.13%( 116/282), that of skeletal flurosis was 47.95%(969/2021) and that of X-ray checked was 20.73% (17/82). The median of urine fluoride was 1.06 mg/L and the scope was 0.20 - 9.44 mg/L.Conclusions Most of the improved-water projects do not normally supply water in the disease ward of Guide county. Therefore, there is an increasing trend of the disease, so further control measures are needed.

Objective To investigate the fulfillment of improved water measures for endemic fluomsis and to find out the trend of prevalence in Qinghai Province in order to provide scientific basis and technical support for the government to formulate control strategies for endemic fluorosis.Methods Usage and management of reforming water facilities in Huzhu County were generally surveyed.Yanya Village,Caijiabu Town,Huzhu County was chosen as the surveillance spot.The household drinking water was surveyed.The dental fluorosis and urine fluoride content of children aged 8-12 years and adult above 16 years were examined.Skeletal fluorosis of adult was checked.The fluomsis content in drinking water and urine was determined with F-ion selective electrode method.The dental fluowsis was examined with Dean index.Skeletal fluorosis was diagnosed according to eountry standard(GB 16396-1996.WS 192-1999).Results The rate of water-improving was 60%(36/60)in Huzhu County.The mean of fluoride content in drinking water Was 1.25 mg/L The prevalence rate of dental fluorosis of children aged 8-12 years was 90.20%(46/51);that of adult was 88.89%(48/54).The dental fluorosis index of children was 1.77,that of adult was 2.95.The prevalence rate of skeletal fluorosis was 98.15% indicated by clinical data,18.87% by X-ray.The ufine fluorosis content of children was 2.27 mg/L,that of adult was 2.00 mg/L.Conclusion The disease condition of endemic fluorosis in Qinshai is serious,defluofidation is slow in effect.

Objective To investigate epidemical situation of drinking-tea fluomsis in Qinghai province, in order to understand diet structure to provide the scientific basis for the prevention and control and the scientific research. Methods In 2007, according to "Scheme for Survey on Epidemical Drinking-tea Fluorosis", we carried out an customized investigation in 28 counties, 3 townships sampled in each county, 2 villages in each township, 50 adults and 50 school-age children in each village; at same time, 1 monk temple was sampled in each county, 50 clergy adults and 50 children in each temple. Then we investigated the resident income, the diet structure, the brick tea consumption and so on, and applied Dean method to diagnose dental fluorosis. The patient number estimated based on the survey result. Results ①Yeady per capita income of people was mostly 500 - < 1000yuan, next 1000 - < 3000 yuan; economic income in pasturing area was higher than that of agriculture, half area and half agriculture and half pastoral region and township. ②Staple food was bread flour primarily in the animal husbandry agricultural half pastoral area,next were the roasted barley and the rice;the bread flour was the principle food in the agricultural region and the cities,next were the rice and the roasted barley;among non-staple food,meat came fimt and milk foHowed,egg the last.③The frequently edible vegetables Was potato.cabbage and greenpepper,eaten by a majority of people[62.82%(6497/10 343)];as for fruits,apple,pear and orange was primarily consumed,75.95%(7856/10 343)of people ate less than 10 times every month.④Sixty-one thousand nine hundred and ninety-nine residents were registered,153 335 kg ofbrick tea was consumed in villages and towns,2.47 kg per person;in 1001 monks investigated,4120 kg of brick tea was consumed every year,4.12 kg per person.⑤Detection rate of adult dental fluorosis in the villages and towns was 24.11%(2494/10 343),that of the children was 24.38% (3012/12 355);detection rate of dental fluorosis in monks was 26.13%(203/777),that of the children was 39.73% (89/224).⑥Detection rate of adult skeletal fluorosis in villages and towns was 15.60%(17/109);that of monks was 4.88%(2/41).⑦The 95%confidence limit estimated a total number of dental fluorosis patients were 1 084 306- 1 134 170 persons.the median Was 1 109 238 persons;the 95% confidence limit estimated a total number of skeletal fluorosis patients were 309 177-758 199 persons,the median was 533 688 persons.Conclusions Qinghai province has a great quantity of brick tea consumption,having lots of people with drinking-tea fluorosis which is in severe degree.The resident food structure was monotonous and mostly transpolted from other region.
