Objective To understand the fairness of health resources of endemic diseases institutions in Henan Province,to provide evidence for endemic allocation of health resources for the government.Methods Health-related data resources in endemic disease prevention and control institutions were collected in Henan Province,including personnel,business space area,the value of equipment,and health funding,etc.The percentages of population distribution and geographical distribution of health resources were calculated; Lorenz curves of demographic fairness and geographic fairness were drawn.According to Lorenz curve (Gini coefficients of the population and the geographical distribution were calculated based on Lorenz curve),Gini coefficients were used to evaluate the fairness of the endemic disease prevention institutions for health resource allocation.Results As can be seen from Lorenz curve,the population fairness of endemic disease prevention and health personnel was the best,but the number of senior officers was less and the total value of equipment owned was low.The geographical fairness of all the indicators of health resources was poorer,and geographic fairness among senior officers was the worst.The Gini coefficient of health technical personnel,senior personnel,undergraduate or above personnel,value of equipments,area of business room and health funding allocation determined by the population distribution was less than 0.4.The health resources were relatively fair and reasonable according to the distribution of population.The Gini coefficients of all the indicators determined by the distribution of geography were higher than those determined by the distribution of population.Furthermore,the geographic Gini coefficient of senior personnel was above 0.4 which was in the vigilance state.Conclusions The equality of health resources determined by population distribution in the institutions for endemic diseases control in Henan is superior to those determined by geographic distribution.The allocations of health resources of endemic diseases control in different areas are unbalanced.

Objective To know the rural doctors' knowledge,belief and practice on iodine deficiency disorders(IDD),as well as their capability on health education communication in Ye County,Henan Province.Methods Semi-structured interviews were conducted among 50 rural doctors in Ye County,Henan Province.Topics covered include:sales of salt purchases,daily supervision and monitoring activities of salt,the health effects of salt,the situation of rural doctors trained,the situation of rural doctors participated in health education and related recommendations.Results ①Twenty-nine of the rural doctors knew exactly the advantage of salt iodization.②Thirty-nine of the rural doctors had taken part in the half quantitative detection of salt once or twice a year and 15 of them knew the supervision activities of salt industry department.③Forty-nine of the rural doctors believed salt iodization was beneficial to health and 48 of them were willing to participate in health education on IDD.④The major ways of their acquiring health knowledge were promotional materials [54.0％ (27/50)],TV [50.0％ (25/50)],and lecture/training [24.0％ (12/50)].⑤Thirty-seven of the rural doctors had taken part in health education on IDD.They were used to use booklets [68.0％ (34/50)],promotional slogan [36.0％ (18/50)],broadcast [24.0％ (12/50)],and doctor consultation [24.0％ (12/50)].⑥Twenty-eight of the rural doctors thought the current health education on IDD was better.They hoped to reduce the price of salt,strengthen supervision,receive more training and health education on IDD.Conclusions The rural doctors remain relatively lack of knowledge on IDD.Rural doctors have the initiative and responsibility to conduct health education on IDD,but their pattern is still a one-way propagation.

Objective To investigate the consumption rate of non-iodized salt,and evaluate the iodine status and goiter prevalence among school children in high water iodine areas of Henan Province from 2014 to 2015.Methods In the 20 counties with high water iodine,one township was randomly selected from each location (east,west,south,north and middle) in each county;secondly,4 villages were selected from each chosen township;thirdly,15 households were selected to collect salt samples from each chosen village.In the 10 chosen counties,one village with high water iodine was selected and water samples were collected;one school was sequentially selected from the chosen village and 100 school children aged 8-10 were chosen to collect their urine samples and measure their thyroid volume.Salt iodine was tested by semi-quantitative method;iodine contents of urine and water were tested by arsenic cerium catalytic spectrophometry;thyroid volume was measured by ultrasound method.Results In the 20 counties with high water iodine,4 440 salt samples were collected and tested both in 2014 and 2015;the rates of non-iodized salt were 98.2％ (4 363/4 440) in 2014 and 98.3％ (4 366/4 440) in 2015.In the 10 chosen counties,the median water iodine contents from the chosen villages were 202.0 μg/L in 2014 and 235.0 μg/L in 2015;970and 999 urine samples of the students from the chosen villages were collected and tested in 2014 and 2015,and the median urinary iodine contents were 251.9 μg/L in 2014 and 290.6 μg/L in 2015;937 and 948 students were examined in 2014 and 2015,the goiter rates were 3.4％ (32/937) in 2014 and 7.8％ (74/948) in 2015.Stratified by water iodine,the urinary iodine contents and goiter rates of school children increased with the rise of water iodine content.When the water iodine content exceeded 300 μg/L,goiter rate of school children was 8.4％,which was higher than other groups (P ＜ 0.05).Conclusions After stopping the supple of iodized salt in high water iodine areas,the current iodine status and goiter rate of school children are still higher than normal levels.Both noniodized salt supply and water improvement to reduce water iodine content should be taken in the areas with water iodine higher than 150 μg/L.

Twenty cDNA differential fragments were isolated from the hippocampus of rats in epileptic state using mRNA differential display technique. Four fragments were sequenced and compared with the known sequences in the Genebank, which showed that ERG8, ERG11, ERG12had no significant identity to any known sequences; ERG14 had 64%-69% identity to microtubulin-associated protein of the rat. Because the differential expression of these genes was caused by epilepsy inducer coriaria lactone (CL) and anti-epilepsy drug MK-801 and ERG8 might be a novel candidate epilepsy gene; ERG11 and ERG12 might be novel candidate anti-epilepsy genes.Since the microtubulin-associated protein is closely associated with the collateral sprouting of mossy fibers in the hippocampus of seizured rat, the high expression of ERG14 in the early stage of epilepsy might predict the growth of axon and formation of synapse.

Objective:To understand the status of drinking water-borne endemic fluorosis in Henan Province, so as to provide scientific basis for improving prevention and control strategies.Methods:Ten counties (districts, referred to as counties) were selected from drinking water-borne endemic fluorosis areas of Henan Province in 2018. Three villages in each project county were selected according to the disease status of mild, moderate and severe conditions, and the operation status of water improvement projects, water fluoride content and dental fluorosis among children aged 8 to 12 years in each diseased village were monitored.Results:Totally 30 villages were surveyed, all of which were in the water improvement projects; a total of 25 water improvement projects were monitored, all of them were in normal operation, and the water fluoride exceeding standard rate was 28.00% (7/25), the qualified rate of water fluoride in the water improvement projects was 72.00% (18/25). Among them, 21 villages were in normal operation and the water fluoride in the water improvement projects met national standard. In which the detection rate of dental fluorosis among children aged 8 to 12 years was 36.71% (606/1 651), the index of dental fluorosis was 0.74, and the epidemic intensity was extremely mild. Water fluoride of water improvement projects in 9 villages exceeded the national standard, where the detection rate of dental fluorosis among children aged 8 to 12 years was 43.57% (261/599), the index of dental fluorosis was 0.78, and the epidemic intensity was extremely mild. The detection rate of dental fluorosis among children in the villages where the water fluoride of water improvement projects exceeded the national standard was higher than that in the villages where the water fluoride of water improvement projects met the national standard (χ 2=8.752, P < 0.01). Conclusions:The excessive fluorine content in the water of water improvement projects is still serious, and the epidemic is still severe. It is necessary to strengthen the scientific demonstration of the water improvement project construction and the project acceptance upon completion, so as to prevent unqualified projects from being put into use. We will carry out regular water quality monitoring and promptly rectify projects with water quality exceeding the standards.

Objective To investigate the iodine nutritional status among children aged 8-10 years old in Henan Province after five years of implementation of new standard iodized salt,and to provide evidence for scientific adjustment of control strategy.Methods In 2017,according to "Henan Surveillance Program on Iodine Deficiency Disorders",children aged 8-10 years old (half males and half females) were chosen as research targets.In nonhigh iodine areas of 156 non-high iodine counties (cities,districts) and high iodine counties (cities,districts) in Henan Province,household salt samples were collected;in 113 counties (cities,districts),urine samples were collected;in 67 counties (cities,districts),thyroid volume was measured.Salt iodine was tested by direction titration,the salt samples from Sichuan and other enhanced salt samples were tested by the arbitration method;urinary iodine was tested by arsenic cerium catalytic spectrophometry;thyroid volume was measured by ultrasound method.Results In 2017,totally 31 174 household salt samples of 8-10 years old children were collected and tested,the median of salt iodine was 25.8 mg/kg;the coverage rate of iodized salt was 95.0％ (29 613/31 174) and the consumption rate of qualified iodized salt was 85.6％ (26 673/31 174).Totally 22 442 urine samples were collected and the median of urinary iodine content was 208.0 μg/L.Totally 13 439 school children were examined thyroid volume and the goiter rate.was 1.5％ (196/13 439).Conclusions After the promotion of new standard iodized salt,the iodine nutritional status of children aged 8-10 years old in Henan Province is appropriate.However,the consumption rate of qualified iodized salt is lower,so the universal salt iodization prevention and control strategies should be performed for a long time.At the same time,health education of iodine deficiency knowledge should be strengthened.

Objective:To investigate the iodine nutritional status of pregnant women in Henan Province after implementation of new standard of iodized salt, and to provide evidence for scientific adjustment of control strategy.Methods:In 2018, according to "Henan Surveillance Program on Iodine Deficiency Disorders", 5 townships were randomly picked out based on their sub area positions of east, west, south, north and middle in each county in the non-high iodine areas of 156 non-high iodine and high iodine counties (cities, districts). Then 20 pregnant women were sampled in each chosen township to collect and determine their salt and urinary iodine contents. The iodine level in salt was determined by direction titration; the salt samples from Sichuan and other enhanced salt samples were detected by arbitration; iodine content in urine was tested by arsenic cerium catalytic spectrophometry.Results:In total, 15 430 household salt samples of pregnant women were collected and determined; the coverage rate of iodized salt was 95.4% (14 721/15 430) and the consumption rate of qualified iodized salt was 87.0% (13 426/15 430); the median of salt iodine was 25.8 mg/kg. Totally 15 378 urine samples were collected and the median urinary iodine was 188.0 μg/L. The medians of urinary iodine of early, middle and late pregnant were 190.2, 188.9 and 186.0 μg/L, respectively.Conclusions:After the implementation of new standard of iodized salt, the iodine nutritional status of pregnant women in Henan Provence is totally appropriate. The surveillance of iodine status and the universal salt prevention and control strategies among pregnant women should be continuously presented to ensure the moderate amount of iodine intake.

Objective:To understand the prevention and control progress of drinking water-borne endemic fluorosis in Henan Province, to evaluate the effects of prevention and control measures, and provide a basis for adjusting prevention and control strategies.Methods:In 2019, a general survey was conducted in all registered drinking water-borne endemic fluorosis villages in Henan Province to monitor the basic conditions of water improvement, the fluoride content of drinking water and the prevalence of dental fluorosis in children aged 8-12 years. The control compliance (water fluoride content qualified and the detection rate of dental fluorosis of children ≤30%) status of the villages was analyzed, and calculate the compliance rate.Results:A total of 17 504 drinking water-borne endemic fluorosis villages were monitored, among them, 17 352 villages with water improvement and 152 villages without water improvement, with a water improvement rate of 99.1%. Among the 3 685 water improvement projects constructed, 3 448 were in normal operation, and the normal operation rate was 93.6%. There were 13 526 villages with qualified drinking water fluoride content, and the qualified rate of water fluorine was 77.3%; the actual beneficiary population was 11 011 000, and the population benefit rate was 90.1%. The qualified rate of water fluoride in the villages with and without water improvement was 77.9% (13 512/17 352) and 9.2% (14/152), respectively; the qualified rate of water fluoride in the villages with water improvement was significantly higher than that in the villages without water improvement (χ 2=400.58, P < 0.05). A total of 498 527 children of 8 to 12 years old were examined, 68 972 cases of dental fluorosis were detected, the detection rate of dental fluorosis was 13.84%, and the dental fluorosis index was 0.3. The number of villages meeting the control standard was 12 488, and the compliance rate was 71.3%. Conclusions:In Henan Province, the water improvement projects in the drinking water-borne endemic fluorosis areas have been basically implemented, and the disease has been effectively controlled. However, there is still a certain gap with the target of the "13th Five-Year Plan on National Prevention and Control of Endemic Diseases", and timely rectification is needed to ensure the effectiveness of the water improvement projects.
