摘要：Supramolecular dendritic polymers（SDPs）provide a new opportunity for the precision diagnosis and treatment of diseases. SDPs are a novel class of non-covalently bonded macromolecules with highly branched structure and three-dimensional globular topology, which exhibit dynamic/reversible features and unique physical/chemical properties（e.g., high solubility, low viscosity, and numerous functional terminal groups）. The reversibility of non-covalent interactions endows SDPs with the ability of facile preparation, smart responsiveness, and simple metabolism. These special characteristics determine the properties of SDPs, which are the key points for theranostic applications, including diagnosis,therapy, and theranostics. In this review, we briefly summarize the design and synthesis of SDPs with aimed structures,properties, functions as well as their present diagnostic and theranostic applications. These developments on the preparation and applications of SDPs for diagnostic and theranostic purpose promote interdisciplinary research fields of chemistry, material and biomedical science.

摘要：The laying quail is a worldwide breed which exhibits high economic value. In our current study, the vas- oactive intestinal peptide receptor-1 （VIPR-1） was selected as the candidate gene for identifying traits of egg produc- tion. A single nucleotide polymorphism （SNP） detection was performed in 443 individual quails, including 196 quails from the H line, 202 quails from the L line, and 45 wild quails. The SNPs were genotyped using a polymerase chain reaction-restriction fragment length polymorphism （PCR-RFLP）. Two mutations （G373T, A313G） were detected in all the tested quail populations. The associated analysis showed that the SNP genotypes of the VIPR-1 gene were sig- nificantly linked with the egg weight of G373T and A313G in 398 quails. The quails with the genotype GG always exhibited the largest egg weight for the two mutations in the H and L lines. Linkage disequilibrium （LD） analysis in- dicated that G373T and A313G loci showed the weakest LD. Seven main diplotypes from the four main reconstructed haplotypes were observed, indicating a significant association of diplotypes with egg weight. Quails with the hlh2 （GGGT） diplotype always exhibited the smallest egg weight and largest egg number at 20 weeks of age. The overall results suggest that the alterations in quails may be linked with potential major loci or genes affecting reproductive traits.

摘要：Objective： To provide guidance for future randomized controlled trials （RCTs） based on a review con- cerning acupuncture for treating polycystic ovary syndrome （PCOS）. Methods： A comprehensive literature search was conducted in October 2015 using MEDLINE, EMBASE, SCISEARCH, Cumulative Index to Nursing and Allied Health Literature, the Cochrane Menstrual Disorders and Subfertility Group trials register, Allied and Complementary Medi- cine （AMED）, China National Knowledge Infrastructure （CNKI）, and the Wanfang databases. RCTs comparing either acupuncture with no/sham/pharmacological intervention or a combination of acupuncture and conventional therapy with conventional therapy in the treatment of PCOS were included in this review. A quality evaluation was performed for each of the included studies. Results： Thirty-one RCTs were included in the review and were divided into four categories according to the type of intervention used in the comparator or control group. Menstrual frequency, hor- mones, anthropometrics, insulin sensitivity, blood lipids, and fertility were used as the main measurements to assess the effects of acupuncture on the patients with PCOS. Thirty trials, except for one, showed an improvement in at least one of the indicators of PCOS after acupuncture treatment. However, normalizing the methodological and reporting format remains an issue. Conclusions： Based upon this review of current clinical trials concerning acupuncture for treating PCOS, we provide guidelines for better clinical trial design in the future.
