ABSTRACT
Objective To understand the characteristics of malaria endemic situation in Dongtai City from 1999 to 2013. Methods The data of diagnosed malaria cases and related information of prevention and treatment were collected and analyzed with the epidemiological method. Results From 1999 to 2013 there were 27 malaria cases in total and among which 2 cases were local-infected with Plasmodium vivax 10 cases were imported P. vivax infections 13 cases were imported P. falciparum infections and 1 case was a mixed infections P. falciparum P. vivax and P. ovale . The imported cases accounted for 92.59%and local-infected cases accounted for 7.41%. There were no local-infected cases after 2003 and all the cases were overseas-im-ported. The main first-diagnosis points were town hospitals and village health stations accounting for 33.33%and 33.33%re-spectively. Totally 62.96%of cases visited the clinic in 1 day after the attacking the median of time-interval from the attacking to visiting the clinic was 1 day the median of time-interval from the attacking to confirmed diagnosis was 3 days and the max time from the attacking to confirmed diagnosis was 33 days. Conclusion The malaria cases are mainly imported cases in Dong-tai City from 1999 to 2013 and therefore the key of eliminating malaria should be the monitoring of the retuned exporting la-bors.
ABSTRACT
Objective To investigate current dietary and dyslipidemia status of air force pilots.Methods Energy expenditure was calculated by using daily-activity-recording method.Dietary survey was performed through weighing method.Body measurements were carried out according to military criteria.Double agent enzymic method was used to detect blood lipid profiles.The results were compared in 1997 and 1982.t or x2 test was used for data analysis.Results Excessive energy consumption and highprotein and fat or low-carbohydrate intake was found in the participants.Energy from fat or carbohydrate accounted for 47.3％ and 37.9％,respectively.Obesity and overweight was found in 20.8％ air force pilots,and hypertriglyceridemia and hypercholesterolemia occurred in 47.9％ and 17.7％,respectively.Conclusion Dietary pattern and energy metabolism are inappropriate in air force pilots as a result of dyslipidemia.
ABSTRACT
The surveillance of schistosomiasis in Dongtai City, Jiangsu Province from 2004 to 2008 showed that the achievements of schistosomiasis control in local were consolidated.
ABSTRACT
Objective To explore the possible effects of nutritional supplements on brain function as reflected by Water Maze test performance in mice after +Gz exposure.Method Mice were arranged into control group (group A),+Gz group without nutritional supplementation (group B) and +Gz plus nutritional supplementation group (group C).Each group contains 12 mice.Mice in group A were not exposed to +Gz while mice in both group B and group C were exposed to 8 min +10 Gz.Distilled water was gavaged to group B mice 3 h before +Gz exposure.On the day before +Gz exposure pyridoxol fortified water was given and 3 h before exposure mixed amino acids solution were gavaged to group C mice.Water Maze test was done and scores were recorded in all groups.After the Water Maze test was completed,blood was collected through the eyes for serum amino acid determinations and brain tissue was collected by decollation for monoamine determination and γ-glutamyl transferase (GGT) activity evaluation. Result After +Gz exposure,longer completion time and more mistakes were observed in Water Maze test in group B as compared with group A and a trend of improvement in group C was noticed. The ratio of brain 5-HT to dopamine(DA) was significantly reduced in group C as compared with group B.Gamma glutamyl transferase (GGT) activity in brain tissue in group C and group B increased significantly. Conclusion High sustained +Gz exposure significantly reduces Water Maze test performance in mice (longer completion time and more mistakes).It seems that there is a trend of improvement in Water Maze performance in mice in dietary nutritional supplementation group,which might be due to significant reduction in ratio of brain 5-HT to DA in mice with nutritional supplementation.
