ABSTRACT
Sepsis is a frequently met syndrome with complex clinical symptoms and high mortality in emergency department. Early diagnosis of sepsis and timely treatment can improve survival. In recent years, the application of biomarkers [such as procalcitonin (PCT), C-reactive protein (CRP), interleukin-6 (IL-6)] are commonly used in the early diagnosis of sepsis, but their specificity and sensitivity are limited because of the long lag of report time. Soluble leukocyte differentiation antigen 14 sub type (sCD14-ST, namely presepsin) is a kind of novel biomarkers. Presepsin has a high specificity and sensitivity in the diagnosis of sepsis. It has some value to evaluate the severity of sepsis, antibiotic treatment of antibiotics, and prognosis of the patients with sepsis, and its latest detection method is fast and accurate, so it has the feasibility of clinical application.
ABSTRACT
BACKGROUND:Stem cel s have the potential to differentiate into various organs and tissues. In recent years, stem cel s have been proved to differentiate into hair fol icles under certain conditions. OBJECTIVE:To review the research progress and prospect of stem cel s differentiating to hair fol icles, thereby providing a reliable basis for clinical treatment of serious hair fol icle injury. METHODS:A computer-based search of PubMed, EMBASE, WanFang, CNKI databases was performed for related articles published between 2013 and 2015, using the keywords of“cel hair, fol icle stem, medicine regenerative, differentiation”in English and Chinese. A total of 207 articles were retrieved, and final y 34 articles were included in result analysis. RESULTS AND CONCLUSION:Stem cel s from different sources al have the ability to differentiate into hair fol icles under certain inductions. However, it is important to seek more scientific and rational methods for the differentiation of stem cel s into hair fol icles based on overcoming their own shortcomings. A great progress has been made in animal experiments and subclinical trials, and even a great breakthrough in some aspects. Further studies on combining the advantages and overcoming the shortcomings of various stem cel s during differentiation are required for the clinical treatment of serious hair fol icle injury.

ABSTRACT
BACKGROUND: Wuhuang oil has a bacteriostatic action to treat burn wound and promote traumatic healing, but the action on inhibition of scars formation remains poorly understood.OBJECTIVE: To investigate the effects of modified Wuhuang oil at different concentrations and administration times on the growth and proliferation of human fibroblasts in vitro.DESIGN, TIME AND SETTING: Comparison observation regarding cytology in vitro was performed at the Burns Institute in the First Affiliated Hospital of Nanchang University between April 2006 and January 2007.MATERIALS: Prepuce specimens were harvested from patients who underwent circumcision in Department of urinary surgery, at First Affiliated Hospital of Nanchang University and Jiangxi Provincial Children Hospital. All patients aged 2-12 years old, and informed consents were obtained from their relatives. Wuhuang oil and modified Wuhuang oil (water-solubility) were offered by Department of Pharmaceutical Preparation in the First Affiliated Hospital of Nanchang University, China. METHODS: Human fibroblasts cultured in vitro were divided into 2 groups at random, experiment and control. Experiment group was treated with 300 g/L Wuhuang oil, while control group with 300 g/L modified Wuhuang oil. Serum-free culture fluid was used to prepare 6 concentrations of oil solution: 0 (blank control), 100, 150, 200, 250, 300 g/L.MAIN OUTCOME MEASURES: MTT assay was used to determine the growth and proliferation of human fibroblasts at 2, 3, 4, 5,6 days; inhibition rate of cell growth was observed at 2, 4, 6, 8, 10 days.RESULTS: Modified Wuhuang oil (0-300 g/L) concentration positively correlated with inhibition of human fibroblast proliferation;the inhibition was not related to culture time. Modified Wuhuang oil (300 g/L) had the greatest inhibition rate of human fibroblasts at 8-10 days, there were significant differences between experiment group and control group (P < 0.01).CONCLUSION: Modified Wuhuang oil has an effective inhibition on the proliferation of human fibroblasts in vitro, and shows a dose-dependent tendency. Compared with Wuhuang oil, 300 g/L modified Wuhuang oil is superior to suppress the growth of human fibroblasts.
