Sepsis, the most common panthogeny, is characterized as multi-system injuries like immune system, inflammatory system and coagulation system, caused by systemic inflammatory response syndrome ( SIRS) and excessive oxidative stress after the invasion of pathogen.Severe cases can lead to multiple organ dysfunction syndrome and even death.Acute kidney injury is an independent risk factor which has an influence on patients'prognosis.Currently, the research of biomarkers of AKI is a significant field.Some new biomarkers are found to be charaterised by early appearance in blood or urine, non-traumatic and sensitivity in recent years, which contribute to their applications in early diagnosis of AKI.At present, the biomarkers of early diagnosis of AKI, such as calprotectin, interleukin-18, neutrophil gelatinase associated lipocalin (NGAL), cysteine protease inhibitor C, kidney injury molecule-1 (KIM-1) and cysteine rich 61, are under study.The current basic research and a few clinical studies show that these indicators may have a better sensitivity .

Objective To study the regulatory T cells (Treg-cell) frequencies in patients with childhood acute leukemia and evaluate its clinical application value by investigating the relationship between the increasing numbers of Treg cells and minimal residual disease of leukemia (MRD), Methods Foxp3-FITC/CD25-PE/CD4-PerCP/CD3-APC four-color staining flow cytometry was established to identify Treg cells. Treg cells frequencies both in 10 healthy controls and in 33 patients with newly diagnosed childhood acute leukemia ( B-ALL 17 cases, T-ALL 9 cases, AML 7 cases) were detected. The possibility of the accumulation of Treg cells being the prognostic marker for acute leukemia was evaluated by comparing the results of Treg cells frequency with that of MRD. Results The percentage of Treg cells in CD+4 CD+3 T cells was M = 8. 09% in normal bone marrows, which was significantly different from the results in the bone marrows of newly diagnosed childhood acute leukemia ( M = 12.77% , U = 3.41, P < 0.01 ), but it showed no significantly differences among B-ALL, T-ALL and AML groups. No association was observed between the expression of Treg cells and clinical-biologic characteristics studied. In addition, Treg cells frequency in MRD positive group was significantly different from that in MRD continuously negative group ( M = 14. 74% vs M=11.3%, t =252.5,P<0.05). Conclusions Consistent with results from solid tumor, the study identifies a significantly increased numbers of Treg cells in patients with childhood acute leukemia. The situation of accumulation of Treg cells is closely associated with MRD results during chnical remission. High level of Treg cells may cause poor prognosis and increase the possibility of relapse.

With the development of natural products, the research activities on the solubilization methods of water-insoluble natural products have been carried out worldwide. Big molecular weight and poor solubility of most natural active ingredients lead to a very poor oral absorption and low bioavailability, which has extremely limited their development in pharmaceutical fields and clinical application. As a result, it is necessary to find out a suitable technique to improve the solubility and enhance the oral bioavailability of insoluble natural drugs. Based on the related references published in these years, this review introduced some new techniques to improve the solubility and bioavailability of natural drugs, including prodrugs, inclusion complex, solid dispersion, cocrystals, osmotic pump, liquisolid compacts, micronization, self-microemulsifying, nanosuspensions, lipsomes, polymeric micelles and so on, and summarized the theory, characteristics, application range, application examples, problems and development direction of each technique.

DAZL, a member of the DAZ family, plays a key role in human spermatogenesis. It regulates the promoter via genetic modification, especially DNA methylation, promoting the transcription of DAZL. Besides, the relation of DAZL SNPs with male infertility has been a hot spot of research for many years. It is deduced that local and ethnic factors may be associated with the failure of spermatogenesis. This article presents an overview on the results of recent studies, changes in the DNA methylation of DAZL in spermatogenesis, and the association of DAZL SNPs with male infertility, aiming to provide a new theoretical basis and clinical strategy for the treatment of male infertility.
