Abstract Blumea balsamifera (L.) DC., a medicinal plant with high economic value in the Asteraceae family, is widely distributed in China and Southeast Asia. However, studies on the population structure or phylogenetic relationships with other related species are rare owing to the lack of genome information. In this study, through high-throughput sequencing, we found that the chloroplast genome of B. balsamifera was 151,170 bp in length, with a pair of inverted repeat regions (IRa and IRb) comprising 24,982 bp, a large single-copy (LSC) region comprising 82,740 bp, and a small single-copy (SSC) region comprising 18,466 bp. A total of 130 genes were identified in the chloroplast genome of B. balsamifera, including 85 protein-coding, 37 transfer RNA, and 8 ribosomal RNA genes; furthermore, sequence analysis identified 53 simple sequence repeats. Whole chloroplast genome comparison indicated that the inverted regions (IR) were more conserved than large single-copy and SSC regions. Phylogenetic analysis showed that B. balsamifera is closely related to Pluchea indica. Conclusively, the chloroplast genome of B. balsamifera was helpful for species identification and analysis of the genetic diversity and evolution in the genus Blumea and family Asteraceae.

Abstract Purpose: To investigate the impacts of albumin synergized with hydroxyethyl starch (HES) on early microvascular albumin leakage after major abdominal surgery in rabbits. Methods: Forty male Japanese rabbits were randomly divided into four groups: the control group, the saline group, the albumin group, and the Syn group (hydroxyethyl starch+albumin). The latter three groups were performed gastrectomy plus resection of pancreatic body and tail and splenectomy. The serum albumin concentration was detected before and 48h after surgery, and the conditions of mesenteric microvascular leakage in these 4 groups were observed under microscope 48 h after surgery to calculate the leakage rate. Results: Compared with the saline group, the albumin group and the Syn group exhibited significantly increased serum albumin concentrations 48h after surgery (P<0.05). The albumin leakage rate was the most obvious in the albumin group, followed by the saline group, while that in the Syn group was the minimal, and there existed significant differences among these groups (P<0.05) . Conclusion: Simple administration of albumin in the early stage after major abdominal surgery could increase the albumin leakage, while the synergization of albumin and hydroxyethyl starch could reduce the albumin leakage.

The millions of persons migrating from China's rural areas to urban spaces have contributed greatly to the country's decades-long economic growth, and the influx of migrants has changed the fabric of China's urban social and economic life. These internal migrants, similar to many international immigrants, depend heavily on their social networks, which are often developed in their rural villages, for jobs, housing, financial assistance, and social support both during and after migration. Consequently, migrants' networks function distinctly in well-being and behavior. Using data from the 2006 China General Social Survey, this article seeks to 1) investigate the existence of migrant sub-groups in China, 2) understand the characteristics of social networks among sub-groups, and 3) explore the relationships social networks hold to life satisfaction and political participation among China's migrant population. This article asserts that China's migrant population includes several sub-groups emerging on the basis of gender, education, age, and marital status, which in turn produce different patterns of ties and social interactions among their social networks. While this article finds very different employment patterns among migrant sub-groups, migrant networks do not appear to strongly influence perceptions and behaviors, such as life satisfaction and political participation. This article also argues that individual networks could facilitate the development of migrant communities in cities.

Durante décadas, millones de personas han emigrado desde las áreas rurales de China hacia las ciudades, y realizado una importante contribución al desarrollo económico del país, cambiando el tejido social y económico de las ciudades. Estos emigrantes internos, al igual que los inmigrantes internacionales, dependen en gran medida de sus redes sociales para encontrar trabajo, vivienda, asistencia financiera, y apoyo social tanto durante como después de la migración, contribuyendo significativamente a su bienestar. A partir de los datos del Encuesta Social General de China del 2006, este artículo 1) describe los diferentes subgrupos de inmigración en China, 2) analiza las características de sus redes sociales, y 3) explora la contribución de éstas a su participación política y satisfacción vital. Este artículo propone clasificar la población emigrante china en subgrupos por razón de género, educación, edad y estado civil, los cuales producen diferentes patrones de conexiones e interacciones entre sus redes sociales. El presente estudio revela patrones de empleo muy diferenciados entre los distintos subgrupos de emigrantes, en cambio sus redes no parecen tener una importante contribución en sus percepciones y conductas, tales como su satisfacción vital y participación política. Este artículo también plantea que las redes personales podrían facilitar el desarrollo de las comunidades de emigrantes en las ciudades.
