ABSTRACT
Objective:To understand the contents of edible salt iodine and urinary iodine of children and pregnant women in Yunnan Province, and to evaluate the iodine nutrition status, so as to provide a basis for scientific prevention and treatment of iodine deficiency disorders (IDD).Methods:From November to December 2020, one county (city) was selected from each prefecture (city), two townships (towns and streets) were selected from each county (city) and two villages (neighborhood committees) were selected from each township (town and street) from each of the 16 prefectures (cities) in Yunnan Province as the investigation sites. A total of 20 non-boarding children (male and female balanced) aged 8 - 10 years old were selected from each primary school in each village (neighborhood committee) to collect salt and urine samples. A total of 80 children were investigated in each county (city). A total of 20 pregnant women were selected from each township (town and street) to collect salt and urine samples. A total of 40 pregnant women were investigated in each county (city). All salt samples and urine samples were tested for iodine contents.Results:A total of 2 009 salt samples and 2 041 urine samples (1 375 for children, 666 for pregnant women) were collected from children aged 8 - 10 years old and pregnant women in 16 counties (cities) of Yunnan Province. Among them, the median salt iodine was 26.0 mg/kg, the coverage rate of iodized salt was 100.0% (2 009/2 009), the qualified rate of iodized salt was 98.7% (1 982/2 009), and the consumption rate of qualified iodized salt was 98.7% (1 982/2 009). The difference of salt iodine content in key populations in different counties (cities) was statistically significant ( H = 258.98, P < 0.01). The median urinary iodine of children aged 8 - 10 years old was 188.5 μg/L. There was statistically significant difference in urinary iodine content among children of different ages ( H = 29.45, P < 0.01), but there was no statistically significant difference in urinary iodine content among children of different genders ( H = 1.43, P > 0.05). In addition, the median urinary iodine of pregnant women was 141.9 μg/L, 52.1% (347/666) was < 150 μg/L. There was statistically significant difference in urinary iodine content of pregnant women in different counties (cities, H = 88.32, P < 0.01). Conclusions:The qualified rate of iodized salt, the coverage rate of iodized salt and the consumption rate of qualified iodized salt in key populations of Yunnan Province are more than 90%, and the iodized salt supply is good. Iodine nutrition of children aged 8 - 10 years old is at an appropriate level (100 - 199 μg/L); iodine nutrition of pregnant women is in an state of iodine deficiency ( < 150 μg/L). It is suggested to strengthen IDD monitoring and health education among key populations, improve residents' awareness of disease prevention, and make scientific iodine supplementation.
ABSTRACT
ObjectiveTo explore the mechanism of Xianglian Huazhuo prescription in the treatment of chronic atrophic gastritis （CAG） based on network pharmacology and animal experiments，so as to provide scientific basis for clinical application. MethodThe possible targets and pathways of Xianglian Huazhuo prescription in the treatment of CAG were obtained based on the prediction of network pharmacology. The CAG rat model was induced by sodium salicylate，N-methyl-N'-nitro-N-nitrosoguanidine （MNNG） and hunger and satiety disorder. Then the CAG rats were treated with Xianglian Huazhuo prescription and morodan for 60 days. After administration，the rats were sacrificed，and the content of interleukin-6 （IL-6），tumor necrosis factor-α （TNF-α），interleukin-1β （IL-1β） and vascular endothelial growth factor （VEGF） in serum was determined by enzyme linked immunosorbent assay（ELISA）. In addition， the protein expression of Bad and Bcl-2 in gastric mucosa was detected by immunohistochemistry （IHC）. ResultA total of 241 active components of Xianglian Huazhuo prescription and 53 core targets were obtained. Xianglian Huazhuo prescription affected multiple biological processes，such as cell proliferation and apoptosis，inflammatory reaction，regulation of DNA metabolism，and cell response to redox，as well as phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt），TNF，mitogen-activated protein kinase （MAPK），cancer and cancer-related signaling pathways. The animal model verification showed that Xianglian Huazhuo prescription lowered the levels of IL-6，TNF-α，IL-1β and VEGF in serum of CAG rats，and reduced the protein expression of Bad and Bcl-2 in gastric tissue. ConclusionXianglian Huazhuo prescription could regulate PI3K/Akt signal pathway and improve gastric mucosal injury in CAG by participating in biological processes such as cell proliferation，apoptosis and inflammation.

ABSTRACT
Objective:To accurately grasp the current status of water iodine distribution in environmental of Yunnan Province, and provide a basis for scientific iodine supplementation.Methods:In 2017, according to the "National Drinking Water Iodine Content Survey Program", a survey of water iodine content was conducted in townships. In 2018, a search survey was carried out for administrative villages with water samples of iodine content > 40 μg/L in drinking water found in previous surveys. In centralized water supply villages, 2 samples of end water were collected. In decentralized or partially decentralized water supply villages, each village was divided into 5 parts: east, south, west, north and center. In villages with more than 50 water sources, 10% of the water sources were selected from each part; villages with less than 50 water sources, one water source was selected from each part; villages with less than 5 water sources, all the water sources were selected to determine the water iodine content. At the same time, the mode of water supply and demographic data were investigated.Results:At the township level water iodine survey, a total of 24 589 water samples were collected from 1 389 townships in 129 counties of 16 prefectures (cities). The median water iodine content of township was 1.3 μg/L, ranging 0.0 - 9.3 μg/L. The population covered by the survey accounted for 53.94% (25 013 804/46 371 207) of the total population of the province. According to the survey results of high iodine villages, 93 administrative villages in 68 townships of 37 counties in 12 prefectures (cities) were surveyed, covering 40 940 households and 208 880 people. A total of 761 samples of drinking water were tested, and the median water iodine content of administrative villages was 1.3 μg/L (ranging 0.0 - 196.8 μg/L). There were 2 administrative villages with iodine higher than 100 μg/L, which were Xiaobona Administrative Village (145.8 μg/L) in Liuchang Township, Xiangyun County, and Dasongshu Administrative Village (196.8 μg/L) in Yangchang Township, Xuanwei City.Conclusions:The iodine content of water in Yunnan Province is generally low, which belongs to the area of environmental iodine deficiency. For the high iodine villages, further investigation should be carried out to clarify the prevention and control measures.

Methods In 2013, five towns were selected from the villages and towns which the defluoridation stove project was implemented and by the end of 2007 defluoridation stove rate was higher than 95%(including 95%), and two natural villages were selected in each township to carry out the investigation. Dental fluorosis was examined of all children aged 8 to 12 of survey points. At least 20 people were selected in each village. At the same time, 20 copies of instant urine samples were collected from these children of half male and half female, and urinary fluoride was determined. Then five natural villages were sampled from all survey points, and permanent residents were divided into25-,35-,45-,55-and≥65groups according to age. Six people were selected from each group with male and female in half who were conducted examination of adult skeletal fluorosis by X-ray. Dental fluorosis diagnosis was based on theDental Fluorosis Diagnosis(WS/T 208-2011). Urinary fluoride determination was done in accordance withUrine-Determination of Fluoride-Ion Specific Electrode Method(WS/T 30-1996). Skeletal fluorosis diagnosis was carried out according to Diagnostic Criteria for Endemic Skeletal Fluorosis (WS 192-2008). Results A total of 556 children aged 8 to 12 were monitored, the detection rate of dental fluorosis was 41.55%(231/556), the dental fluorosis index was 0.78. The very mild, mild, moderate and severe proportions of children's dental fluorosis were 20.50%(114/556), 17.09%(95/556), 3.60%(20/556) and 0.36%(2/556), respectively, given priority to very mild. The prevalence of dental fluorosis in children was increased with increasing age (χ2=74.27, P<0.05). One hundred and ninety-three copies of child urine samples were tested, the geometric mean of urinary fluoride was 0.62 mg/L, and the urinary fluoride contents were between 0.10-2.93 mg/L. A total of 116 adults were examined, and the detection rate of skeletal fluorosis was 9.48%(11/116). Detected cases of skeletal fluorosis was given priority to mild (9 cases, accounted for 81.81%), more men cases [16.36% (9/55)] than those of women [3.28% (2/61), χ2 = 5.77, P< 0.05]. Conclusion The hazard of coal-burning type fluorosis has been reduced in Fuyuan County , the affect of defluoridation stove project is obvious.

Objective To explore the role of Kupffer cells in high fat diet induced hepatic insulin resistance. Meth-ods Eighty-four C57BL/6J mice were divided into two groups: normal chow (NC) group (7 subgroups) and high fat diet (HFD) group (7 subgroups). Glucose tolerance tests were performed at feeding time of 1,2,4,8,12 and 16 weeks in one NC group and one HFD group. The mice livers at the same feeding time were obtained in other 6 NC groups and 6 HFD groups respectively. The expression levels of IRS1-ser307, Akt-ser473, S6K1-thr389 and p-JNK were detected by Western blot as-say. The values of MCP-1,TNF-α,IL-1βand IL-10 mRNA were examined by qRT-PCR. Results Compared with NC group, the impaired glucose tolerance was found from the first week in HFD group (P ＜ 0.05). The hepatic expressions of IRS1-ser307, S6K1-thr389 (4-16 weeks ) and p-JNK(2-16 weeks ) increased and Akt-ser473(8-16 weeks )decreased in HFD group than those of NC group. The same results were gained by analysis of protein relative expression (all P＜0.05). The hepatic pro-inflammatory factor MCP-1,TNF-αand IL-1βmRNA expressions were higher in HFD group than those in NC group during 2-16 weeks (all P ＜ 0.01). The anti-inflammatory factor IL-10 mRNA was significantly lower in HFD group than that in NC group during 4-16 weeks (all P＜0.01). Conclusion High fat diet maybe play a role in the hepatic insulin resistance by stimulating M1 Kupffer cells to secrete pro-inflammatory factor and inhibiting M2 Kupffer cells to se-crete anti-inflammatory factor.
ABSTRACT
OBJECTIVE@#To compare the effect of rehabilitation of prelingual deaf children who used a cochlear implant (CI) in one ear and a hearing aids in the opposite ear while the hearing level of the opposite ears are different. Hearing ability, language ability and learning ability was included in the content. The aim of this research is to investigate better style of rehabilitation, and to offer the best help to the prelingual deaf children.@*METHOD@#Accord ing to the hearing level of the ear opposite to the one wearing a cochlear implant and whether the opposite ear wear a hearing aid or not, 30 prelingual deaf children were divided into three groups, including cochlear implant with opposite severe hearing loss and hearing aid ear (CI+SHA), cochlear implant with opposite profound hearing loss and hearing aid ear (CI+PHA), cochlear implant only (CI). The effect of rehabilitation was assessed in six different times (3,6,9,12,15 and 18 months after the cochlear implants and hearing aids began to work).@*RESULT@#The longer time the rehabilitation spends, the better the hearing ability,language ability and the learning ability were. The hearing ability of CI+SHA was better than those of CI+PHA (P<0.05) and CI (P<0.05). The language ability and learning ability of CI-SHA was nearly equal to those of the other two groups.@*CONCLUSION@#The prelingual deaf children should take much more time on rehabilitation. The effect of rehabilitation for prelingual deaf children who used cochlear implant in one ear and hearing aid in the other depend on the residual hearing level of the other ear. If a prelingual deaf children still has any residual hearing level in the ear opposite to the cochlear implant ear, it is better for him/her to wear a hearing aid in the ear.
