Objective:To understand the situation and distribution of fluoride in rural centralized water supply in Inner Mongolia Autonomous Region (Inner Mongolia for short), and provide a reference for adjustment of prevention and control measures.Methods:From 2014 to 2018, 836, 947, 1 033, 1 068, 1 099 rural centralized water supply monitoring sites were designated in 77 banners (counties, districts) separately in Inner Mongolia, and factory water and tip water samples were collected during plentiful phase and exhausted phase every year, respectively, and fluoride content was tested. Descriptive analysis was done according to time, water period (plentiful phase and exhausted phase), water sample type (factory water and tip water), water treatment method (conventional treatment, sedimentation and filtration, only disinfection and untreated), area distribution [eastern region (Hulunbuir, Xing'an League, Tongliao and Chifeng), central region (Hohhot, Baotou, Ulanqab and Xilinhot) and western region (Ordos, Bayannur and Alashan)], and the results were analyzed visually by ArcMAP 10.2.Results:From 2014 to 2018, 3 251, 3 671, 4 058, 4 087 and 4 395 water samples were collected, the medians fluoride were 0.69, 0.70, 0.69, 0.64 and 0.66 mg/L, and the annual compliance rates of fluoride were 80.31% (2 611/3 251), 81.83% (3 004/3 671), 83.14% (3 374/4 058), 85.91% (3 511/4 087) and 84.57% (3 717/4 395). The difference of compliance rate of fluoride in rural centralized water supply in different years was statistically significant (χ 2=51.748, P < 0.01), and the compliance rate of fluoride showed an increasing trend with the years (χ 2=41.140, P < 0.01). The compliance rates of fluoride in plentiful phase and exhausted phase were 83.36% (8 128/9 750) and 83.29% (8 089/9 712), respectively, and the difference was not significant statistically (χ 2=0.020, P > 0.05). As for water sample type, the compliance rates of fluoride in factory water and tip water were 83.55% (6 583/7 879) and 83.17% (9 628/11 576), and the difference was not significant statistically (χ 2=0.485, P > 0.05). The difference of compliance rate of fluoride in different water treatment methods was statistically significant (χ 2=192.014, P < 0.01). The compliance rates of fluoride in water with conventional treatment and only disinfection were higher [95.51% (404/423) and 94.44% (986/1 044)]; and the untreated water had the lowest compliance rate of fluoride [81.75% (13 073/15 991)]. There was a statistically significant difference in compliance rates of fluoride in the eastern, central and western regions (χ 2=629.256, P < 0.01), with the eastern region had the highest compliance rate of 89.17% (7 337/8 228); the central region had the lowest compliance rate of 74.67% (5 391/7 220). The visualization results showed that the compliance rate of fluoride was obviously low in the central region north of Yin Mountains and west of Greater Higgnan Mountains. Conclusions:From 2014 to 2018, the compliance rates of fluoride in rural centralized water supply increase year by year, and some achievements have been made in fluorine reduction and water improvement project in Inner Mongolia. However, there are still some rural areas with low level of water fluoride compliance rates which mainly distribute in the central region of Inner Mongolia in the north of Yin Mountains and west of Greater Higgnan Mountains. The current focus of prevention and control should be shifted from "general control" to "precise fluorine control". In the future, it is necessary to implement treatment projects in key areas of fluorine pollution from the aspects of policy implementation and technological innovation to ensure the drinking water safety of local rural residents.

OBJECTIVE To compare the effect between drug donation model and national drug negotiated model on drug sales,and to provide reference for pharmaceutical enterprises to optimize their business strategies . METHODS Based on medical insurance statistics and settlement data of city A in Jiangsu province from 2013 to 2018,trastuzumab was selected as the representative drug . The sales and utilization of trastuzumab were compared during the implementation of the two models . At the same time ,the changes of medication behavior of some patients were analyzed . RESULTS After the implementation of drug donation model ,sales volume and turnover of trastuzumab increase by 193.87% and 155.71% in that year compared with the previous year ,and then the growth trend became stable ;after including the national negotiated drug list ,the number of users of trastuzumab in the year increased by 87.68% compared with the previous year ,and the sales volume increased by 48.06%;turnover increased by 22.81% even though the unit price decreased significantly . Both models could improve drug sales ,and the results of multiple linear regression also proved that different models had a significant impact on the consumption sum of trastuzumab in patients. CONCLUSIONS Under the condition that the unit price level of drugs is approximately the same ,both drug donation model and national drug negotiated model can increase the sales volume and expand the coverage of drugs . The latter reduces the drug threshold of patients ,and plays a positive role in improving the drug accessibility of patients and the sales and development of enterprises.

Objective To investigating the microbial communities and physicochemical properties of soil and distribution of Oncomelania hupensis snails in marshlands along the Yangtze River basin at different types of land use, and to examine the effects of soil microorganisms and physicochemical properties on snail distribution, so as to provide insights into snail control and schistosomiasis prevention in marshland along the Yangtze River basin. Methods Marshlands with four types of land use were selected along the Yangtze River basin on April 2021, including poplar forest-crops integrated planting, reed areas, agricultural cultivation lands and ditches. The distribution of snails and physicochemical properties of soil were investigated in marshlands with different types of land use, and the V3 to V4 regions of the bacterial 16S ribosomal RNA (16S rRNA) gene, fungal internal transcribed spacer-1 (ITS1) gene and algal ribulose-bisphosphate carboxylase (rbcL) gene in soils were subjected to high-throughput sequencing. The occurrence of frames with living snails and density of living snails were compared in marshland with different types of land use. The associations of soil microorganisms and physicochemical properties with the density of living snails were examined using Pearson correlation analysis, and the contributions of soil microorganisms and physicochemical properties to the density of living snails were evaluated using variance partitioning analysis. Results In marshlands with four types of land use, the greatest occurrence of frames with living snails [(4.94 ± 2.14)%] and density of living snails [(0.070 ± 0.026) snails/0.1 m2] were seen in ditches, and the lowest were found in [(1.23 ± 1.23)%] agricultural cultivation lands [(0.016 ± 0.019) snails/0.1 m2]. A total of 2 phyla, 5 classes, 8 orders, 9 families and 11 genera of algae were detected in soils at four types of land use, with Chlorophyta as the dominant phylum and Pseudoneochloris as the dominant genus. A total of 44 phyla, 134 classes, 281 orders, 338 families and 516 genera of bacteria were detected in soils at four types of land use, with Proteobacteria and Acidobacteriota as the dominant phyla and uncultured Acidobacterium, MND1, Mitrospira, Haliangium and Sphingomonas as dominant genera. A total of 11 phyla, 41 classes, 108 orders, 223 families and 408 genera of fungi were detected in soils at four types of land use, with phyla Ascomycota, Basidiomycota and Mortierellomycota presenting high relative abundances and genera Cladorrhinum, Mortierella and Humicola presenting high relative abundances. Pearson correlation analysis revealed that the density of living snails correlated negatively with the relative abundance of Proteobacteria (r = −0.965, P < 0.05) and soil electronic conductivity (r = −0.962, P < 0.05) and positively with soil moisture (r = 0.951, P < 0.05). Variance partitioning analysis demonstrated that the physicochemical properties and microorganisms of soil contributed 69% and 10% to the density of living snails, respectively. Conclusion The diversity of microbial communities varies in soils at different types of land use in marshland along the Yangtze River basin, and the physicochemical properties and microorganisms of soils may affect the distribution of O. hupensis snails.
