ObjectiveTo evaluate the association between Pro12Ala polymorphism in peroxisome proliferator activated receptorγ2 (PPARγ2) gene and gestational diabetes mellitus(GDM).Methods Publications on genetic association studies of PPARγ2 and GDM were searched using the PubMed database, The HuGE Navigator, China National Knowledge Infrastructure (CNKI), Wanfang database and VIP Science from the inception of the databases to December 1, 2014. Two reviewers independently selected literature according to the inclusion and exclusion criteria, extracted data and assessed the quality of the data using the Newcastle-Ottawa Scale (NOS) standard. Meta-analysis was performed using RevMan 5.3 software.ResultsOverall, 13 eligible articles were identified, including seven in English and six in Chinese, with a total of 2 787 GDM cases and 5 408 healthy controls. Quality assessment showed that the quality of the 13 articles was all good, with NOS≥5. (1) Pro12Ala polymorphism in PPARγ2 (allele Ala or genotype Ala/Ala or Pro/Ala) was shown to be highly associated with GDM occurrence on general evaluation, with anOR(95%CI) of 0.74(0.60-0.93) in the allele model and 0.79(0.65-0.96) in the dominant genetic model (P<0.05, respectively). (2) Pro12Ala polymorphism in PPARγ2 was shown to be highly associated with GDM occurrence in Asians in a stratification analysis of ethnicity in the populations included in the studies, with anOR(95%CI) of 0.61(0.48-0.79) in the allele model and 0.64(0.50-0.82) in the dominant genetic model (P<0.01, respectively). No correlation was found between the Pro12Ala polymorphism in PPARγ2 and GDM in the Caucasian population. (3) A meta-analysis of six Chinese studies showed that the Pro12Ala polymorphism in PPARγ2 was associated with the risk of GDM in the Chinese population, with anOR(95%CI) of 0.52 (0.36-0.73) in the allele model and 0.55(0.39-0.80) in the dominant genetic model (P<0.01, respectively). (4) No significant association was observed in the TaqMan allelic discrimination assay with anOR(95%CI) of 0.96(0.83-1.10) in the allele model and 0.95(0.81-1.11) in the dominant genetic model (P>0.05, respectively), although there was still a significant correlation in polymerase chain reaction-restriction fragment length polymorphism with anOR(95%CI) of 0.58(0.43-0.79) in the allele model and 0.62(0.45-0.85) in the dominant genetic model (P<0.01, respectively).ConclusionsThe Ala allele and the Ala/Ala or Pro/Ala genotypes of the Pro12Ala polymorphism in PPARγ2 can decrease the risk of GDM. However, there are differences in the results which are affected by the genotype analysis method or races.

BACKGROUND:
AND PURPOSE: Previous studies have explored the association between retinal vascular changes and cognitive impairment. The retinal vasculature shares some characteristics with the cerebral vasculature, and quantitative changes in it could indicate cognitive impairment. Hence, a comprehensive meta-analysis was performed to clarify the potential relationship between retinal vascular geometric changes and cognitive impairment.
METHODS:
Relevant databases were scrupulously and systematically searched for retinal vascular geometric changes including caliber, tortuosity, and fractal dimension (FD), and for cognitive impairment. The Newcastle-Ottawa Scale was used to evaluate the methodological quality of included studies. RevMan was used to perform the meta-analysis and detect publication bias. Sensitivity analyses were also performed.
RESULTS:
Five studies that involved 2,343 subjects were finally included in the meta-analysis. The results showed that there was no significant association between central retinal artery equivalents (Z=1.17) or central retinal venular equivalents (Z=1.74) and cognitive impairment (both p>0.05). Similarly, no significant difference was detected in retinal arteriolar tortuosity (Z=0.91) and venular tortuosity (Z=1.31) (both p>0.05). However, the retinal arteriolar FD (mean difference: −0.03, 95% CI: −0.05, −0.01) and venular FD (mean difference: −0.03, 95% CI: −0.05, −0.02) were associated with cognitive impairment.
CONCLUSIONS
A smaller retinal microvascular FD might be associated with cognitive impairment. Further large-sample and well-controlled original studies are required to confirm the present findings.

OBJECTIVE:To provide reference for accelerating the process of prescription outflow in China by using “Internet+ medicare”. METHODS :Based on stakeholder perspective ,the stakeholder model of prescription outflow was constructed under the background of “Internet + ”. By analyzing stakeholders (hospital,patient,government,drugstore and third-part consultation platform)who impeded the prescription outflow and their demands ,the obstacles and causes of promoting prescription outflow under the background of “Internet+”were summarized to put forward relevant countermeasures and suggestions. RESULTS & CONCLUSIONS:“Internet+Medicare”accelerated the process of prescriptions outflow by improving the convenience in each links of medical treatment ,but there were still obstacles in prescription source ,patient flow ,supporting policies and system construction to continue promoting prescription outflow. The reason lied in the pressure of hospital operation and the diagnosis demand of doctors;the treatment demand of patients could not be satisfied by the receiving party of prescription outflow ;the difficulty of government supervision and system construction ;immature supervision mode of the third-party consultation platform and online pharmacies,and the platform technology research and development to be break through. To continue promoting prescription outflow under the background of “Internet + ”needs to strengthen top-level design ,establish supporting systems ,break the regional restrictions,build a unified and standardized prescription circulation information platform ;formulate the prescription outflow assessment standard and encouragement mechanism of hospital ,enhance the ability of the third-part platforms and pharmacies to undertake the prescription ,strengthen the publicity and education of patients ,enhance their channel awareness and risk awareness. The exploration mode of prescription outflow in which all stakeholders develop together and cooperate with each other is formed finally so as to promote the outflow of prescription.

OBJECTIVE:To put forward some suggestions for the implementation of OTC monograph in China. METHODS : Literature research was used to comprehensively review the concept ,emergence and development ,function of OTC monograph in USA;referring to experience in USA ,the necessity and feasibility of monograph system for OTC registration and evaluation in China were explored ,and some suggestions were put forward to the implementation of OTC monograph in China. RESULTS & CONCLUSIONS:OTC monograph in USA refers to the regulatory standards that should be followed when selling OTC products not included in new drug applications. The monograph originates from the re-evaluation project of the effectiveness of OTC drugs , which plays a special role in accelerating the drug marketing and promoting product innovation. The OTC monograph system is necessary to help to optimize the OTC registration and evaluation ,but at present ,the conditions to establish and implement OTC monograph are not yet ripe in China. Based on the optimization of resource allocation and infrastructure construction ,national OTC drug management experience ,OTC monograph can play a full part in OTC registration and evaluation ,in terms of carrying out in-depth research ,taking pilot test ,improving risk management system and enhancing drug review resource allocation ability.

Metastasis is the leading cause of death in breast cancer patients. However, the mechanisms underlying metastasis are not well understood and there is no effective treatment in the clinic. Here, we demonstrate that in MMTV-PyMT, a highly malignant spontaneous breast tumor model, IL-25 (also called IL-17E) was expressed by tumor-infiltrating CD4 T cells and macrophages. An IL-25 neutralization antibody, while not affecting primary tumor growth, substantially reduced lung metastasis. Inhibition of IL-25 resulted in decreased type 2 T cells and macrophages in the primary tumor microenvironments, both reported to enhance breast tumor invasion and subsequent metastasis to the lung. Taken together, our data suggest IL-25 blockade as a novel treatment for metastatic breast tumor.
