Two new bisamides from the leaves of Aglaia perviridis

Two new bisamides, aglaiamides A (1) and B (2), along with three known ones (3–5), were isolated from the leaves of Aglaia perviridis. Their structures were established on the basis of detailed spectroscopic analyses.     

Protocol for the development of consensus-based clinical case reporting guideline extension: CARE for acupuncture

BackgroundHealth research reporting guidelines for case reports (CARE - CAse REport) published in 2013 and 2017 have become a generally accepted standard for publishing case reports. The CARE guidelines represent an architectural framework for writing an evidence-based case report that can be customized as need for a specialty (or disease) if needed. We aim to develop a CARE guideline extension for acupuncture following the EQUATOR Network (Enhancing the QUAlity and Transparency Of health Research) and the 2010″Guidance for Developers of Health Research Reporting". We have established a group of international experts including; clinicians, researchers and methodologists. We performed a needs assessment based on a review of acupuncture case reports published in the indexed medical literature. The needs assessment will be followed by (1) a series of expert interviews to establish a draft, (2) a modified Delphi process, and (3) a consensus meeting. Following the consensus meeting we will pilot test the CARE draft before publishing the CARE extension for acupuncture.MethodsWe will develop the CARE extensions for acupuncture following recommendations of the EQUATOR Network and the 2010 "Guidance for Developers of Health Research Reporting". We will establish an international multidisciplinary group including clinical practitioners, acupuncturists, researchers of reporting guidelines on acupuncture, clinical epidemiologists and statisticians.We performed a needs assessment, reviewing published case reports using acupuncture as a therapeutic intervention from indexed medical journals (PubMed-PMC and Medline, Scopus, Embase, the Allied and Complementary Medicine Database (AMED), Cumulative Index to Nursing and Allied Health Literature (CINAHL), Wan Fang database, Chinese BioMedicine database (CBM), China National Knowledge Infrastructure (CNKI), and VIP). In consultations with advisors we will develop a draft of potential items to be included in the CARE extension for acupuncture. Then we will conduct a modified Delphi process of at least three rounds, hold a face-to-face consensus meeting, pilot test and submit the CARE extension for acupuncture for publication.ConclusionThe development of a widely accepted CARE extension for acupuncture for case reports published in indexed medical journals. These guidelines will follow the EQUATOR Network recommendations and the 2010 "Guidance for Developers of Health Research Reporting".     

H型高血压患者舌面诊图像颜色特征参数分析＊

目的 分析H型高血压患者的舌面诊图像颜色参数特征，探讨H型高血压患者的舌诊、面诊变化规律。方法 运用上海中医药大学自行研制的Smart TCM-1型中医舌面一体仪，采集高血压患者舌面诊图像，提取特征参数，分析健康对照组、H型高血压组与非H型高血压组患者舌面颜色参数特征。结果 ①在舌色各项参数中，H型高血压组舌尖部R值、B值、V值均显著小于健康对照组（P < 0.01）；非H型高血压组舌尖部B值显著小于健康对照组（P < 0.01），S值较健康对照组显著增大（P < 0.05）；H型高血压组舌尖部R、V值均明显小于非H型高血压组（P < 0.05）。在舌苔各项参数中，H型高血压组舌中H值、V值均明显小于健康对照组（P < 0.05）；非H型高血压组舌中V值、舌右V值均显著小于健康对照组（P < 0.01）；H型高血压组舌中H值明显小于非H型高血压组（P < 0.05），右侧舌苔S值明显大于非H型高血压组（P < 0.05）。②H型高血压组面色参数鼻G值、下颌G值、口唇R值、口唇V值均明显小于健康对照组（P < 0.05）；非H型高血压组前额H值、目眶H值、脸颊H值、鼻H值、下颌H值、整体H值均明显大于健康对照组（P < 0.05）；H型高血压组前额H值、目眶G值、目眶H值、脸颊H值、鼻G值、鼻H值、下颌R值、下颌G值、下颌H值、下颌V值、口唇R值、口唇G值、口唇V值、整体R值、整体G值、整体H值、整体V值均明显小于非H型高血压组（P < 0.05）。结论 H型高血压患者苔色偏黄，以舌中部为主，且舌右侧黄苔积聚较明显；H型高血压患者面色为黄中带红，口唇、下颌部更为晦暗。H型高血压患者的舌、面诊特征参数的变化，与高血压病阳亢湿盛病机相符。     

Carboxylesterase catalyzed 18O-labeling of carboxylic acid and its potential application in LC-MS/MS based quantification of drug metabolites

LC-MS quantification of drug metabolites is sometimes impeded by the availability of internal standards that often requires customized synthesis and/or extensive purification. Although isotopically labeled internal standards are considered ideal for LC-MS/MS based quantification, de novo synthesis using costly isotope-enriched starting materials makes it impractical for early stage of drug discovery. Therefore, quick access to these isotope-enriched compounds without chemical derivatization and purification will greatly facilitate LC-MS/MS based quantification. Herein, we report a novel ¹⁸O-labeling technique using metabolizing enzyme carboxylesterase (CES) and its potential application in metabolites quantification study. Substrates of CES typically undergo a two-step oxygen exchange with H₂¹⁸O in the presence of the enzyme, generating singly- and doubly-¹⁸O-labeled carboxylic acids; however, unexpected hydrolytic behavior was observed for three of the test compounds – indomethacin, piperacillin and clopidogrel. These unusual observations led to the discovery of several novel hydrolytic mechanisms. Finally, when used as internal standard for LC-MS/MS based quantification, these in situ labeled compounds generated accurate quantitation comparable to the conventional standard curve method. The preliminary results suggest that this method has potential to eliminate laborious chemical synthesis of isotope-labeled internal standards for carboxylic acid-containing compounds, and can be developed to facilitate quantitative analysis in early-stage drug discovery.

Looking Ahead in Renal Cell Carcinoma: Integrating New Agents in the Armamentarium of the Urologist

Urologists play a pivotal role in many aspects of the care of patients with renal cell carcinoma (RCC). However, until recently, in some European countries, they have rarely been involved in the systemic treatment of this disease or in the design of clinical trials. This is undoubtedly set to change with the emergence of new oral, molecularly targeted therapies for RCC. Sorafenib (Nexavar^®; Bayer Healthcare, West Haven, CT, USA) is one such therapy, which has already been shown to be efficacious and well tolerated for the treatment of RCC. Although targeted agents show great promise for the treatment of RCC, their precise role in the treatment of metastatic disease, and in adjuvant and neoadjuvant settings has yet to be defined. Drawing from their extensive experience of RCC, urologists will be instrumental in the design and application of clinical studies to define the role of targeted therapies in all settings of RCC and, ultimately, to integrate targeted therapies into clinical practice. Through increased understanding of the molecular pathways involved in RCC, research into diagnostic and prognostic markers, and commitment to clinical trials, urologists can be at the forefront of this progress.     

Polymorphic distribution of Y-chromosome haplotype and mitochondrial DNA in the Bouyei people in China

In the evolution of humans, many kinds of mutations in the human genome have been accumulated, providing credible genetic evidence for the study of human origins and migrations. The "out-of-Africa" hypothesis of modern human evolution and the genetic origin of the Japanese has come about by studying mitochondrial DNA.l,2 Recently, researchers have recognized the power of Y-chromosome markers in resolving migratory patterns of modern humans as more and more Y-chromosome single nucleotide polymorphism markers have been found. The markers on the nonrecombinant part of the Y-chromosome allows for the reconstruction of intact haplotypes which are probably the best genetic tools to study human migrations. We can analyze the paternal history of some people in different areas by Y-chromosome haplotypes.     

Kinetics of the phenotype and function of murine peritoneal macrophages following acute inflammation

This study was undertaken to have a better understand for the process and the underlying mechanisms to limitmacrophage activation and population of activated macrophages.A comprehensive kinetics of cytokineproduction was performed in murine peritoneal macrophages recovered from Balb/c mice at various timeduring the course of an intraperitoneal injection with thioglycollate (TG).The expression of cell surfacemolecules such as MHC-Ⅰ,MHC-Ⅱ,B7-1 and B7-2 of these macrophages were also determined by flowcytometry.The present findings of our research suggested that the population of activated macrophages and theactivation of macrophages (including cytokines production and expression of cell surface functional molecules)were strictly controlled during inflammation process.This is one of the important mechanisms to retain the hosthomeostasis.Cellular & Molecular Immunology.2004;1(1):57-62.
