The distribution information of Cistanche deserticola was collected by interview investigation and field survey, and 55 related environmental factors were collected, the habitat suitability study was conducted based on geographic information system (GIS) and Maximum entropy model. The AUCs of ROC curve were both above 0.9, indicating that the predictive results with the maxent model were highly precise. The results showed that 14 major environmental factors have obvious influence on ecology suitability distributions of C. deserticola, including vegetation type et al, the suitable distribution areas are mainly concentrated in the central of Alxa Youqi, the north of Alxa Zouqi and the south-east of Ejin Banner, including Tamusu towns, Alateng towns et al, The zoning results basically coincide with the genuine producing areas, and further afford new suitable distribution areas, which can provide reference for the siting of introduction and cultivation of C. deserticola.

Fluorescence intraoperative cholangiography (IOC) is a potential alternative for identifying anatomical variation and preventing iatrogenic bile duct injuries by using the near-infrared probe indocyanine green (ICG).However,the dynamic process and mechanism of fluorescenceIOC have not been elucidated in previous publications.Herein,the optical properties of the complex of ICG and bile,dynamic fluorescence cholangiography and iatrogenic bile duct injuries were investigated.The emission spectrum of ICG in bile peaked at 844 nm and ICG had higher tissue penetration.Extrahepatic bile ducts could fluoresce 2 min after intravenous injection,and the fluorescence intensity reached a peak at 8 min.Inaddition,biliary dynamics were observed owing to ICG excretion from the bile ducts into the duodenum.Quantitative analysis indicated that ICG-guided fluorescence IOC possessed a high signal to noise ratio compared to the surrounding peripheral tissue and the portal vein.Fluorescence IOC was based on rapid uptake of circulating ICG in plasma by hepatic cells,excretion of ICG into the bile and then its interaction with protein molecules in the bile.Moreover,fluorescence IOC was sensitive to detect bile duct ligation and acute bile duct perforation using ICG in rat models.All of the results indicated that fluorescence IOC using ICG is a valid alternative for the cholangiography of extrahepatic bile ducts and has potential for measurement of biliary dynamics.

Objective To assess the effect of health education delivered in different mannersfor hospitalized patients with acute cerebral infarction (ACI). Methods The hospitalized ACI patientsadmitted in our department in 2006 were divided randomly into two groups. In one group, the patientsreceived a booklet on stroke in addition to oral health education (group A), and in the other, only has oraleducation was administered (group B). Questionnaires were issued before, immediately and 7 days afterthe education to survey their basic knowledge of stroke and compliance to medication. ResultsAltogether 612 patients were involved in the study, and the two groups showed no significant differencesin gender, age and educational level. In the test of stroke knowledge, the correct rate of the answersincreased significantly after the health education in both groups (P<0.001), without significant differencesbetween the two groups. The correct rate of group A was significantly higher than that of group B 7 daysafter the education (P<0.001). Compared with group B, the patients in group A showed better complianceto medication 6 months after the education. Conclusion Combination of written and oral healtheducation may achieve better compliance to the medical advices in patients with ACI.

This paper investigates and counts the ethnic medicines of the Ewenki,Daur and Oroqen ethnic groups,which are known as the " Three Minorities" in Inner Mongolia. Through the methods of literature collection,interview investigation,and resource investigation,different ethnic medicines were collected on the main diseases,drug varieties,drug-injection sites,and drug administration methods. Through data statistics and SPSS analysis,the similarities and individual differences between the three ethnic groups were clarified. The results indicated the predicament of the current national medicine,which is helpful for the protection and inheritance of ethnic medicine.

OBJECTIVES: To investigate the clinical treatment outcomes and the changes of the outcomes over time in extremely preterm twins in Guangdong Province, China. METHODS: A retrospective analysis was performed for 269 pairs of extremely preterm twins with a gestational age of <28 weeks who were admitted to the department of neonatology in 26 grade A tertiary hospitals in Guangdong Province from January 2008 to December 2017. According to the admission time, they were divided into two groups: 2008-2012 and 2013-2017. Besides, each pair of twins was divided into the heavier infant and the lighter infant subgroups according to birth weight. The perinatal data of mothers and hospitalization data of neonates were collected. The survival rate of twins and the incidence rate of complications were compared between the 2008-2012 and 2013-2017 groups. RESULTS: Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of severe asphyxia and smaller head circumference at birth (P<0.05). The mortality rates of both of the twins, the heavier infant of the twins, and the lighter infant of the twins were lower in the 2013-2017 group compared with the 2008-2012 group (P<0.05). Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of pulmonary hemorrhage, patent ductus arteriosus (PDA), periventricular-intraventricular hemorrhage (P-IVH), and neonatal respiratory distress syndrome (NRDS) and a higher incidence rate of bronchopulmonary dysplasia (P<0.05). CONCLUSIONS There is a significant increase in the survival rate over time in extremely preterm twins with a gestational age of <28 weeks in the 26 grade A tertiary hospitals in Guangdong Province. The incidences of severe asphyxia, pulmonary hemorrhage, PDA, P-IVH, and NRDS decrease in both the heavier and lighter infants of the twins, but the incidence of bronchopulmonary dysplasia increases. With the improvement of diagnosis and treatment, the multidisciplinary collaboration between different fields of fetal medicine including prenatal diagnosis, obstetrics, and neonatology is needed in the future to jointly develop management strategies for twin pregnancy.

In this paper, angelica broken wall powder(ABWP) was taken as the research object, HPLC fingerprint combined with multi-component determination(ferulic acid, senkyunolide I, coniferyl ferulate, ligustilide and 3-butylidenephthalide), physical fingerprint(D_(90), particle size distribution range, particle size distribution width, bulk density, tap density, inter-particle porosity, Carr index, specific surface area, pore volume, angle of repose, Hausner ratio, loss on drying and hygroscopicity)were used to characterize the quality attribute of ABWP; similarity analysis, cluster analysis, principal component analysis and orthogonal partial least squares discriminant analysis were conducted to construct the quality evaluation method of holographic analysis based on traditional Chinese medicine QbD "4 H mode", in order to evaluate the quality of ABWP from different sources and find out differentiated indicators. The quality evaluation method could be used for scientific, comprehensive evaluation of the quality attribute of ABWP, and the quality consistency evaluation of cell-wall-broken powder of different sources or different processes.It provides new ideas for quality control and research of ultrafine granular powders of traditional Chinese medicine.
