Objective To know the current situation of drinking water quality and the influencing factors of provided for oneself water supply in rural schools in Guangxi.Methods According to the randomly proportionate stratification (economic,geography and topography etc.),43 and 50 counties were selected in 2007 and 2008 and the monitoring sites from 3 rural schools with provided for oneself water supply facility were taken out based on the proportion of water sources and technical patterns coverage in each county.The survey on water supply technical patterns,water sources and their coverage was conducted.One hundred and thirty,one hundred and fifty-three monitoring sites in rain season (July or August) and dry season (March or November) were monitored separately in 2007 and 2008.The monitoring results of drinking water were assessed according to Sanitary Standards for Drinking Water Quality (GB5749-2006).Results The groundwater was main drinking water source,which were 84.03% and 90.75% in 2007 and 2008.Most of water supply had not any water treatment,which was 75.86% in 2007 and 64.22% in 2008.The qualified rate in rain season (18.02%) was significant lower than dry season (31.80%) (P

Objective To investigate the quality of drinking water produced by safe drinking water projects in rural areas of Guangxi.Methods A survey of water quality was conducted from January to October 2008,in the drinking water projects funded by treasure bonds in 89 counties (cities and districts) of Guangxi.The water samples were collected from waterworks and tap water in dry season (March) and rainy season (July to August),respectively,and evaluated for aesthetic,microbiologic and chemical indexes.Results A total of 1 327 drinking water projects were surveyed.58.25% had a daily output under 100 tons,and only 2.71% had an output over 1 000 tons (enough for 10 000 persons).Only 12.28% adopted comprehensive water treatment process (i.e.coagulation,sedimentation,filtration and disinfection),whereas 62.85% did not provide any treatment.Up to 79.80% had no disinfection equipment and 90% failed to provide effective disinfection.25.21% and 21.48% of finished water,and 25.78% and 20.59% of tap water samples tested up to the standard respectively in the dry season and rainy season.Over 88% of water samples met the aesthetic,chemical and toxicological standards (100% up to standard for chronic,arsenic and fluoride),while 73.16%-80.78% met the standard for bacterial count,30.86%-36.17% for fecal coliforms and 41.86%-47.73% for thermotolerant coliforms.Conclusion The study results indicate that the inadequate supply of safe water,absence of water treatment facilities and poor drinking water quality have represented a potential health risk in Guangxi rural areas.

Objective To know the drinking water quality,latrine improvement and fecal,domestic garbage,sewage treatment in the rural areas in Guangxi Province.Methods The survey was carried out according to "National Scheme on Current Situation of Rural Drinking Water and Sanitation" from July to December,2006.The water samples were collected in rain season(August 2006).2 414 houses were investigated in 241 administrative villages of 23 counties.Results In the rural population,31.66% was served by central supply,68.34% was served by non-central supply in Guangxi Province.22.22% of the people used surface water and 77.78% used ground water.The eligible rate of water quality was 21.58%.As for surface water,the eligible rate was 32.76%,as for ground water,it was 18.03%.As for central water supply,the eligible rate was 24.06%,as for non-central water supply,it was 18.52%.The eligible rate of total count of bacteria and total coliform was only 62.24% and 29.88% respectively.The sanitary latrine rate was only 43.79%.The treatment rate of domestic garbage was 45.57%,industrial garbage was 80.17%.No domestic sewage was treated,the treatment rate of production wastewater was very low(only 1.59%).Conclusion The drinking water quality and sanitation in the rural areas in Guangxi Province should be improved as early as possible.

Objective To understand and master the dynamic changes and contributing factors to Guangxi rural drinking water quality. Methods No less than 25% of counties in Guangxi Zhuang Autonomous Region were randomly selected according to the proportional stratified sampling method to build the monitoring network for the dynamic monitoring of rural drinking water quality. The sampling time was arranged in the rainy (July or August) and dry season (March or November) in 2007 and 2008, respectively. The test methods were those documented in the standard (GB 5750-2006). Results The coverage rate of rural centralized water supply was 35.72% in 2008, higher than that in 2007 (31.80%) by 3.92%; the eligible rate of water quality in 2007 and 2008 were 20.57% and 24.59% respectively. The eligible rate of water quality in dry season was higher compared with that in the rainy season. Among all the monitoring indexes, the microbiological index ranked the lowest in terms of eligible rate, ranging from 34.76% to 80.68% for central water systems, and from 21.43% to 66.57% for non-central water supply. Conclusion Microbiological pollution is the main influencing factor for drinking water quality in rural areas in Guangxi Zhuang Autonomous Region.

Objective:To study the effect of naoxintong capsules combined with nerve growth factor on the serum levels of interleukin-6 (IL-6),matrix metalloproteinase-9 (MMP-9) and S100B of patients with hypertensive intracerebral hemorrhage.Methods:88 patients with hypertensive intracerebral hemorrhage who were treated in our hospital from August 2015 to July 2016 were selected and randomly divided into the observation group and the control group The patients in the control group were treated with nerve growth factor,while the patients in the observation group were treated with naoxintong capsules combined with nerve growth factor.Then the clinical efficacy,GCS,GOS score,serum levels ofIL-6,MMP-9 and S100B were observed and compared between the two groups.Results:After treatment,the total effective rate in the observation group was significantly higher than that the control group (P＜0.05).After treatment,the GCS and GOS scores of the two groups were significantly higher than before,and the GCS and GOS of the observation group were higher than those of the control group (P＜0.05).After treatment,the serum levels of IL-6,MMP-9 and S100B in the two groups were significantly lower than before,and the observation group were lower than those of the control group (P＜0.05).There was adverse reactions in the two groups.Conclusion:Naoxintong capsule combined with nerve growth factor can reduce the serum levels of IL-6,MMP-9 and S100B in patients with hypertensive intracerebral hemorrhage,with obvious clinical curative effect and high safety.
