BACKGROUND:Autologous bone marrow mesenchymal stem cel s can treat decompensated liver cirrhosis, however, little evidence has addressed the control ed clinical research in hepatitis B patients with decompensated live cirrhosis.
OBJECTIVE:To evaluate the clinical efficacy and safety of autologous bone marrow mesenchymal stem cel s in the treatment of hepatitis B with decompensated live cirrhosis.
METHODS:A total of 67 hepatitis B patients with decompensated live cirrhosis were divided into two groups according to their wishes to receive stem cel transplantation. The control group (34 patients) only received oral administration of nucleoside analog antivirus and supportive treatment. The treatment group (33 patients) received autologous bone marrow mesenchymal stem cel s transplantation via hepatic artery plus antivirus and supportive treatment. The liver functional index, clinical signs and symptoms, adverse reactions were observed and compared at 4, 12, 24 weeks after treatment.
RESULTS AND CONCLUSION:After treatment, al patients’ symptoms were improved to varying degrees. After 4 weeks of treatment, the liver functional indexes were al significantly improved compared with before treatment, the levels of alanme aminotransferase, cholinesterase and prothrombin activity in treatment group were significantly ameliorated compared with control group (P<0.05). At 12 and 24 weeks of treatment, the alanme aminotransferase, albumin, total bilirubin, cholinesterase and prothrombin activity in control group and treatment group showed statistical y significant differences compared with before treatment (P<0.05). At the same time point, al the indicators in the treatment group were significantly ameliorated compared with control group (P<0.05). The Child-pugh score and model for end-stage liver disease score declined at 4, 12, 24 weeks after treatment, showing significant differences compared with before treatment. The difference was also significant at the same time point between two groups. The treatment of nucleoside analogue antivirus combined with autologous bone marrow mesenchymal stem cel s transplantation on hepatitis B patients with decompensated liver cirrhosis is an effective method to improve liver function and blood coagulation function, with symptom improvement, safety and low risk.

Objectives To study the prevailing status of coal-burning type endemic fluorosis in Fuyuan County of Yunnan Province, and to provide a scientific basis for fluorosis control and prevention. 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 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.

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.

Objective:To analyze the influencing factors of thyroid volume in children aged 8 - 10 in Yunnan Province, and provide scientific basis for improving iodine deficiency disorders monitoring.Methods:From March to July 2020, in 129 counties (cities, districts) under the jurisdiction of Yunnan Province, each county (city, district) was divided into 5 sampling areas based on east, west, south, north, and middle. One township was selected from each area, and 40 non-boarding children aged 8 - 10 from one primary school were selected from each township (age balanced, half male and half female) as survey subjects. One random urine sample and household edible salt samples were collected for urine iodine and salt iodine testing, and physical examination and thyroid volume measurement were conducted for children. The influencing factors of thyroid volume were analyzed using Pearson correlation.Results:A total of 24 934 urine samples were collected from children, with a median urine iodine of 233.2 μg/L. A total of 24 933 household edible salt samples were collected from children, the median salt iodine was 24.17 mg/kg, and the qualified rate of iodized salt was 96.63% (24 003/24 839); A total of 24 937 children were examined of their thyroid gland, with a median thyroid volume of 2.62 ml and a goiter rate of 1.12% (280/24 937). Among them, there were 12 410 boys and 12 527 girls, with thyroid volumes of 2.61 and 2.64 ml, respectively. The thyroid volume of boys was positively correlated with age, height, weight, body mass index, body surface area, and salt iodine ( r = 0.15, 0.21, 0.26, 0.18, 0.25, 0.03, P < 0.001). The thyroid volume of girls was positively correlated with age, height, weight, body mass index, and body surface area ( r = 0.17, 0.26, 0.28, 0.17, 0.27, P < 0.001). Conclusion:Children aged 8 - 10 in Yunnan Province are at an iodine excess level; the age, weight, height, body mass index, and body surface area are influencing factors of thyroid volume.
