OBJECTIVE To standardize the main processes and related technical links of the clinical comprehensive evaluation of drugs， and provide guidance and reference for improving the quality of comprehensive evaluation evidence and its transformation and application value. METHODS The construction of Guideline for the Workflow of Clinical Comprehensive Evaluation of Drugs was based on the standard guideline formulation method of the World Health Organization （WHO）， strictly followed the latest definition of guidelines by the Institute of Medicine of the National Academy of Sciences of the United States， and conformed to the six major areas of the Guideline Research and Evaluation Tool Ⅱ. Delphi method was adopted to construct the research questions； research evidence was established by applying the research methods of evidence-based medicine. The evidence quality classification system of the Chinese Evidence-Based Medicine Center was adopted for evidence classification and evaluation. The recommendation strength was determined by the recommendation strength classification standard formulated by the Oxford University Evidence-Based Medicine Center， and the recommendation opinions were formed through the expert consensus method. RESULTS & CONCLUSIONS The Guideline for the Workflow of Clinical Comprehensive Evaluation of Drugs covers 4 major categories of research questions， including topic selection， evaluation implementation， evidence evaluation， and application and transformation of results. The formulation of this guideline has standardized the technical links of the entire process of clinical comprehensive evaluation of drugs， which can effectively guide the high-quality and high-efficient development of this work， enhance the standardized output and transformation application value of evaluation evidence， and provide high-quality evidence support for the scientific decision-making of health and the rationalization of clinical medication.

Polymyxin B, which is a last-line antibiotic for extensively drug-resistant Gram-negative bacterial infections, became available in China in Dec. 2017. As dose adjustments are based solely on clinical experience of risk toxicity, treatment failure, and emergence of resistance, there is an urgent clinical need to perform therapeutic drug monitoring (TDM) to optimize the use of polymyxin B. It is thus necessary to standardize operating procedures to ensure the accuracy of TDM and provide evidence for their rational use. We report a consensus on TDM guidelines for polymyxin B, as endorsed by the Infection and Chemotherapy Committee of the Shanghai Medical Association and the Therapeutic Drug Monitoring Committee of the Chinese Pharmacological Society. The consensus panel was composed of clinicians, pharmacists, and microbiologists from different provinces in China and Australia who made recommendations regarding target concentrations, sample collection, reporting, and explanation of TDM results. The guidelines provide the first-ever consensus on conducting TDM of polymyxin B, and are intended to guide optimal clinical use.

Compared with empirical dosing, it can improve the safety, effectiveness, economy, and adherence of pharmacotherapy of warfarin. This consensus report describes the commonly used modeling and simulation techniques for warfarin, their application in developing and adjusting dosing regimens, medication adherence and economy. Moreover, this consensus also elaborates the detailed procedures for the implementation in the warfarin pharmacy service pathway to facilitate the development and application of model informed precision dosing for warfarin.

Model informed precision dosing (MIPD) is a new concept to guide precision dosing for individual patient by modeling and simulation based on the available information about the individual patient, medications and the disease. Compared to the empirical dosing, MIPD could improve the efficacy, safety, economics and adherence of the pharmacotherapy according to the individual's pathophysiology, genotyping and disease progression. This consensus report provides a brief account of the concept, methodology and implementation of MIPD as well as clinical decision supporting systems for MIPD. The status and future advancing of MIPD was also discussed to facilitate the appropriate application and development of MIPD in China.

OBJECTIVES: Contrast-induced acute kidney injury (CI-AKI) is the third cause of hospital-acquired AKI, and existing clinical prevention and treatment measures such as hydration therapy and/or administration of antioxidants N-acetylcysteine treatment and other treatments still show little effect on the prevention and treatment of CI-AKI. This study aims to explore the effect of Danhong injection on prevention of CI-AKI. METHODS: A total of 12 867 patients, who received coronary angiography, percutaneous coronary intervention, enhanced CT or vascular intervention in a tertiary hospital, were enrolled for this study. Among them, 423 in the treatment group received intravenous drip of Danhong injection, and 12 444 in the control group received routine medicine. Propensity score matching was conducted to balance confounding factors between the 2 groups and then the prevention effect of Danhong injection on CI-AKI was compared between them. RESULTS: A total of 423 pairs of patients were matched successfully. The incidence of CI-AKI in the non-Danhong control group was higher than that in the Danhong treatment group (5.7% vs 2.4%). The difference between the 2 groups was statistically significant ( CONCLUSIONS The results of this study support the use of Danhong injection in the prevention of the Stage 1 of CI-AKI.

High mobility group box 1 (HMGB1) is a nuclear protein that can bind to DNA and act as a co-factor for gene transcription. When released into extracellular fluid, it plays a proinflammatory role by acting as a damage-associated molecular pattern molecule (DAMP) (also known as an alarmin) to initiate innate immune responses by activating multiple cell surface receptors such as the receptor for advanced glycation end-products (RAGE) and toll-like receptors (TLRs), TLR2, TLR4 or TLR9. This proinflammatory role is now considered to be important in the pathogenesis of a wide range of kidney diseases whether they result from hemodynamic changes, renal tubular epithelial cell apoptosis, kidney tissue fibrosis or inflammation. This review summarizes our current understanding of the role of HMGB1 in kidney diseases and how the HMGB1-mediated signaling pathway may constitute a new strategy for the treatment of kidney diseases.

OBJECTIVETacrolimus (FK506) is an immunosuppressive drug, which is widely used to prevent rejection of transplanted organs. However, chronic administration of FK506 leads to hypertension in solid organ transplantation patients, and its molecular mechanisms are much more complicated. In this review, we will discuss the above-mentioned molecular mechanisms of FK506-induced hypertension in solid organ transplantation subjects.

DATA SOURCESThe data analyzed in this review were mainly from relevant articles without restriction on the publication date reported in PubMed. The terms "FK506" or "tacrolimus" and "hypertension" were used for the literature search.

STUDY SELECTIONOriginal articles with no limitation of research design and critical reviews containing data relevant to FK506-induced hypertension and its molecular mechanisms were retrieved, reviewed and analyzed.

RESULTSThere are several molecular mechanisms attributed to FK506-induced hypertension in solid organ transplantation subjects. First, FK506 binds FK506 binding protein 12 and its related isoform 12.6 (FKBP12/12.6) and removes them from intracellular ryanodine receptors that induce a calcium ion leakage from the endoplasmic/sarcoplasmic reticulum. The conventional protein kinase C beta II (cPKCβII)-mediated phosphorylation of endothelial nitric oxide (NO) synthase at Thr495, which reduces the production of NO, was activated by calcium ion leakage. Second, transforming growth factor receptor/SMAD2/3 signaling activation plays an important role in Treg/Th17 cell imbalance in T cells which toget converge to cause inflammation, endothelial dysfunction, and hypertension following tacrolimus treatment. Third, the activation of with-no-K(Lys) kinases/STE20/SPS1-related proline/alanine-rich kinase/thiazide-sensitive sodium chloride co-transporter (WNKs/SPAK/NCC) pathway has a central role in tacrolimus-induced hypertension. Finally, the enhanced activity of renal renin-angiotensin-aldosterone system seems to play a crucial role in the pathophysiology of FK506-induced hypertension.

CONCLUSIONFK506 plays a predominant role in the pathophysiology of hypertension in solid organ transplantation subjects.
