ABSTRACT
OBJECTIVE： To investigate the proportion of 8 kinds of ginsenoside to ginsenoside Rg1 in Panax ginseng and the regularity of growth year in Jilin province， and to provide reference for the identification of growth year. METHODS： The samples of garden ginseng， wild-cultivated ginseng and wild ginseng were collected from different growth years （3-30 years） in Jilin province. The contents of 8 ginsenoside （ginsenoside Rg1， Re， Rf， Rb1， Rc， Rb2， Rb3， Rd） in P. ginseng were determined by HPLC. The contents of saponins as well as the proportion of 8 kinds of ginsenoside to ginsenoside Rg1 were calculated； the relationship of the proportion with growth year was investigated. RESULTS： As the increase of growth year， the proportion of 8 kinds of ginsenosides in garden ginseng to ginsenoside Rg1 as well as that of ginsenoside Re， Rb1， Rc， Rd to ginsenoside Rg1 were decreased gradally （P＜0.001）； the proportion of ginsenoside Re to ginsenoside Rg1 in wild-cultivated ginseng decreased first and then increased（P＜0.001）； the proportion of 8 kinds of ginsenosides to ginsenoside Rg1 as well as the proportion of ginsenoside Re and Rb1 to ginsenoside Rg1 were increased gradually in wild ginseng （P＜0.001）； the proportion of ginsenoside Rf， Rb3 to ginsenoside Rg1 in garden ginseng， wild-cultivated ginseng and wild ginseng had no significant difference（P＞0.05）. CONCLUSIONS： Garden ginseng， wild-cultivated ginseng and wild ginseng contain 8 kinds of ginsenosides. The growth year can be predicted preliminarily according to the proportion of ginsenoside Rg1 and ginsenoside Re， Rb1 to ginsenoside Rg1.
ABSTRACT
Objective To understand the epidemic status of clonorchiasis sinensis in western region of Jilin Province, so as to provide the evidence for formulating the planning and strategy of prevention and control of the disease. Methods In 2017, the areas where the residents had the customs of eating Sashimi were selected as the research areas in the western region of Jilin Province, and according to the cluster sampling, 25 villages in 25 towns (each village per town) of 5 counties in the region were selected as the investigation points. The basic information of crowd was collected by a questionnaire investigation. The Kato-Katz method was used for etiological examinations. The results were analyzed statistically. Results A total of 4 980 people in the 25 villages were investigated, and 1 220 people were infected with Clonorchis sinensis. The average infection rate was 24.50%. There was a significant difference among different counties (cities, districts) in the infection rate of C. sinensis (P < 0.01), and the infection rate in Daan City was the highest (53.82%). In addition, there were significant differences between/among the gender, nation, age, educational level, and occupation in the infection rate (all P values < 0.01). The infection rate of the male was higher than that of the female, the rate of Han was higher than that of other ethnic groups, the rate of the high age group was higher than that of the low age group, the rate of the college degree group was higher than that of the other educational level groups, the rate of the cadre was higher than that of the other occupation groups, and the rate of the group who had vermifuge before the investigation was lower than that of the group who did not have vermifuge. Conclusions The western region of Jilin Province is still the highincidence area of clonorchiasis sinensis. Therefore, the comprehensive control and prevention measures, such as giving vermifuge and health education, should be strengthened in key population and areas in the future.

Methods: The subjects were selected through multi-stage proportional cluster random sampling method. In the eastern, central and western regions of JUin province, a total of 90 townships (towns, streets) in 15 counties (cities, districts) were selected as the survey sites. A retrospective study was conducted on all the children bom from 1 October 2008 to 30 September 2013 in all the survey sites. A total of 48 720 samples were collected from 0 - 5 years old children in Jilin province, 291 samples were excluded, and 48 429 were valid samples. The self-designed questionnaire was used for survey, Epi Data 3. 1 software was used for the entry of data, SPSS 21. 0 Statistical software was used for the statistical analysis. χ2 test was used to compare the incidence of birth defects of the children. Results: There were 48 429 effective samples and 517 cases of them were defected children. The total incidence of birth defects of the children aged 0 - 5 years in Juin province was 10. 68 %o. The incidence of boys (11. 52%o) was higher than that of girls (9. 56%0)χ2 -83. 768, P<0. 01). The incidence of birth defects of the children in countryside (11. 87%o) was higher than that in tovyn (9. 64%0) (χ2=5. 651, P=0. 017). The top five kinds of diseases vyith high incidence of birth defects were congenital heart disease, Polydactyly (toe), congenital hydrocephalus, cleft lip and cleft palate, and spina bifida. Conclusion: The incidence of birth defects of the children aged 0 - 5 years old in Jilin province is at a low level, and the differences in the incidence of birth defects between genders and urban and rural is significant (Congenital heart disease has the highest detection rate in birth defects in juin province.
ABSTRACT
At the urgent practical issue of resource protection and artificial cultivation area selection of Dioscorea nipponica, the dominant environmental factors affecting the distribution of D. nipponicain Jilin province were selected by field investigation and using the maximum information entropy model and geographic information technology. MaxEnt model study found that the standard deviation of seasonal variation of temperature, precipitation in October and other six environmental factors on the growth of D. nipponica are the greatest impacting factors. The range of suitability for the growth of D. nipponica was 4.612 08×10-6-0.544 31, and the regionalization study was divided into four parts: high fitness area, middle fitness area, low fitness area and unfavorable area. The high fitness area is concentrated in the central and southern areas of Jilin Province, using ArcGIS statistical environment factors in the appropriate area of the numerical situation. The results showed that the regionalization study of D. nipponica was basically the same as the actual situation. It is clear that the natural environment suitable for the growth of D. nipponica is also the basis for the protection of the resources and the selection of cultivated area.
ABSTRACT
Chlamydia psittaci is a causative agent of psittacosis,which can infect a wide range of hosts including birds and humans.However,information regarding C.psittaci infection in pigeons is scarce.In the present study,a total of 399 fecal samples from pigeons were collected from Jilin Province,northeastern China,between March and May 2015,and examined by nested PCR amplification of outer membrane protein A (ompA) gene.The overall Chlamydiosis prevalence was 5.01％ (21/399),with 3.19％ in Changchun City and 9.40％ in Jilin City.Furthermore,breed was the major risk factor associated with Chlamydia infection in pigeon,boiler pigeons had a prevalence of 7.49％,whereas no C.psittaci was detected in racing pigeons.Sequence analysis of the ompA gene revealed that all the identified isolates represented C.psittaci genotype B.Our results firstly indicated the presence of zoonotic C.psittaci in boiler pigeons in Jilin Province,northeastern China,and effective measures should be implemented to reduce the risk of C.psittaci transmission from pigeons to humans.
