This article summarizes the present researches on biology of human Demodex about the methods of examination,morphology of adult parasite,biological habits and characteristics,and in vitro survival.

We explored the status of Bartonella infection in rodents and the sequence characteristics of Bartonella in Fujian Province.Rodents in Fujian Province were captured by the night trapping method during 2014-2016.Information of the captured rodents on capturing dates and geographic locations,species,gender and ages were recorded.Heart blood samples were collected,from which the fragments of ghA gene and16S-23S rRNA gene of Bartonella were amplified by polymerase chain reaction (PCR).The PCR products were sequenced and the phylogenetic tree was constructed for homology analysis by biological analysis software.Data on infection rate were analyzed with Chi-square or Fisher exact test to indicate statistical significance.Results showed that 5 917 cages were laid and 381 rodents were captured,density of rodent was 6.44％.The overall Bartonella infection rate in rodents was 12.34 ％,while infection rate in domesticated rodents was 10.61％,with 11.30 ％ in Rattus norvebicus and 10.00％ in R.flavipectus.And the infection rate in wide rodents was 13.86％,with a rate of 22.86％ in Rattus losea and 18.00％ in R.fulvescens,respectively.The infection rate was higher in wild rodents than in domesticated rodents,however,no significant difference was found.The Western Fujian and Northern Fujian region had the higher infection rates of 20.00％ and 25.33％,and no infection was found in Southern Fujian region.The statistical analysis result revealed that a significant difference in infection rate among different region and habitats,but no significant difference in infection rate between male and female rodents,or among different ages.The BLAST results revealed the species to be B.tribocorum,B.elizabethae and B.grahamii.In conclusion,Bartonella infection is found in the rodents in Fujian Province and more attention should be paid on its impact on public health in the province.

Objective:To explore the rules of Traditional Chinese Medicine (TCM) prescriptions of gastroesophageal reflux disease based on Ancient and Modern Medical Records Cloud Platform.Method:The relevant medical cases from ancient medical case database, modern medical case database, shared medical case database and famous doctors' medical case database in Ancient and Modern Medical Records Cloud Platform (V2.3.8) were selected, and frequency analysis, attribute analysis, association analysis, cluster analysis and complex network analysis were performed on the herbs.Results:A total of 107 medical records were obtained, including 225 TCMs. The core medicines were Radix et Rhizoma Glycyrrhizae, Pericarpium Citri Reticulatae, Rhizoma Coptidis, Poria, and Fructus Evodiae. The drug property was mainly cold and warm, and the herbal tastes bitter and pungent. The meridian tropism of drugs mainly manifested in the spleen and stomach meridians. The core herbal pairs were Radix et Rhizoma Glycyrrhizae and Pericarpium Citri Reticulatae. The core prescription consisted of 17 herbs including Radix Glycyrrhizae, Pericarpium Citri Reticulatae, Rhizoma Coptidis, Fructus Evodiae, Poria, Endoconcha Sepiae, Herba Taraxaci, Fructus Aurantii, Radix Paeoniae Alba, Radix Bupleuri, Jiang Banxia, Rhizoma Cyperi, Radix Aucklandiae, Caulis Bambusae In Taenia, Fructus Aurantii Immaturus, Fructus Amomi, and Rhizoma Atractylodis Macrocephalae. Conclusions:Chinese medicine treatment of gastroesophageal reflux disease is mainly based on Chaihu Shugan Powder, Zuojin Pill, and Wendan Decoction. Moreover, we need to combine with clinical symptoms to add or subtract herbs.
