Objective To evaluate the value of serum granulocyte colony-stimulating factor(G-CSF),interlukin-8(IL-8)and white blood cell count(WBC)in detecting acute surgical bacterial infections.Methods A total of 36 patients with infections and 32 with traumatic diseases admitted in Beijing Tongren Hospital without use of antibiotics before admission were recruited,as well as 30 normal healthy controls.Three milliliters of peripheral blood were collected from each of them.Serum G-CSF and IL-8 were measured by enzyme-linked immunosorbent assay(ELISA).Results Of all the 68 patients,serum G-CSF Was(82±71)ng/L in average in those with infections,significantly higher than that in those with trauma(15±7)ng/L(P＜0.01)and controls(7±4)ng/L(P＜0.01).Conclusions Serum G-CSF may be used as a sensitive indicator for acute surgical bacterial infections.

BACKGROUND:Stem cel transplantation has been shown to have many advantages in treatment of diseases. Its application can treat various diseases in many systems such as nervous system, immune system and endocrine system. Its advantage is incomparable. These are al credit to the special abilities, including easy sample colection, strong self proliferative ability, wide differentiation range, repair of injured tissue and immunoloregulation. OBJECTIVE:To explore the clinical effects of stem cel transplantation in treatment of nonunion. METHODS:A computer search was performed in CNKI database for articles concerning stem cel transplantation for nonunion published from 2005 to 2014. The key words were stem cels, nonunion in Chinese. 244 articles were analyzed, and typical literatures were further compared. RESULTS AND CONCLUSION:Stem cels have the abilities of self-renewal and differentiation. Their source is not limited, and the sample colection is convenient. Stem cels have smal injury to the donor, do not have immunogenicity, and have fewer complications. The cost is low. Stem cels are easily isolated and cultured, can proliferate infinitely, and provide a pathway for severe bone injury such as nonunion, bone defects and comminuted fracture. The deep study of stem cels creates a new direction for nonunion treatment, and has achieved certain results in clinical trials.

Circulating tumor cells (CTCs) are present in the peripheral blood,and play an important role in the recurrence and metastasis of lung cancer.As the researches about CTCs and targeted therapy move along,it is found that CTCs can be used as a liquid tumor tissue to guide clinical treatment and have a certain significance in the clinical staging and prognosis evaluation of lung cancer.

BACKGROUND:Health has been paid more and more attention in modern society, the health of those special groups, such as the elderly and the disabled, should also be brought to the forefront. As fitness equipment is more and more popular in contemporary, our focus should be transferred to the use of fitness equipment for these special groups.
OBJECTIVE:To put forward the design strategy of fitness equipment control interface, for the special groups to use common fitness equipment comfortably and conveniently.
METHODS:Based on the research of existing fitness equipment control interface, according to the usage habits and cognitive awareness of special groups on control interface, a new design strategy has been put forward using the general design method and ergonomics.
RESULTS AND CONCLUSION:Based on the existing 45 kinds of exercise bikes, 84 kinds of running machines and 129 kinds of treadmil fitness equipments, we found that these equipments are designed for common users in the aspects of design and production process and control interface. Universal design is a design concept beyond the lack of capacity to meet the different needs of different populations, and designed products can reduce or even eliminate the difference in the ability of special populations and the general population in use. The new strategy makes design of fitness equipment control interface generalized and good man-machine interactive, which can meet the demand of the special groups and help them do fitness exercise to improve their health and body function.

A case of overseas imported quartan malaria was reported in Weihai City. The patient worked in Africa for many years had no blood transfusion history and had not been to malaria endemic regions of China. In approximately half a month af?ter returning from Africa the patient appeared suspected malaria symptoms such as irregular fever sweating and headache. The patient was diagnosed as quartan malaria by a blood test in basic hospital reviewed with a microscope by Weihai Centre for Disease Control and Prevention and checked through the microscopic examination of malaria diagnosis and reference laboratory and PCR amplification by Shandong Institute of Parasitic Diseases. The patient was cured after the treatment with chloroquine/primaquine for 8 days and did not recur in the 3?month following up.

Due to the scarcity of resources of Ziziphi spinosae semen (ZSS), many inferior goods and even adulterants are generally found in medicine markets. To strengthen the quality control, HPLC fingerprint common pattern established in this paper showed three main bioactive compounds in one chromatogram simultaneously. Principal component analysis based on DAD signals could discriminate adulterants and inferiorities. Principal component analysis indicated that all samples could be mainly regrouped into two main clusters according to the first principal component (PC1, redefined as Vicenin II) and the second principal component (PC2, redefined as zizyphusine). PC1 and PC2 could explain 91.42%of the variance. Content of zizyphusine fluctuated more greatly than that of spinosin, and this result was also confirmed by the HPTLC result. Samples with low content of jujubosides and two common adulterants could not be used equivalently with authenticated ones in clinic, while one reference standard extract could substitute the crude drug in pharmaceutical production. Giving special consideration to the well-known bioactive saponins but with low response by end absorption, a fast and cheap HPTLC method for quality control of ZSS was developed and the result obtained was commensurate well with that of HPLC analysis. Samples having similar fingerprints to HPTLC common pattern targeting at saponins could be regarded as authenticated ones. This work provided a faster and cheaper way for quality control of ZSS and laid foundation for establishing a more effective quality control method for ZSS.

Objective To analyze the risk factors of laryngeal carcinoma.Methods The data of laryngeal carcinoma inpatients of our hospital from October 2005 to November 2007 were reviewed retrospectively by a case control analysis.Results The males who have smoking addiction,alcohol consumption,family history of malignant tumor and have more risks to suffer from laryngeal carcinoma.For The family history,OR is 2.01 in the single factor analysis,and in the multivariate analysis the OR is 2.27.Conclusion Gender,smoking,alcohol and family history of malignant tumor have great effect on the risk of laryngeal carcinoma.Family history of malignant tumor is an independent risk factor.

Objective:To build the model of the gene FKBP38 (FK506 binding protein 38) conditional knock out in liver.Methods:Transgenic mouse whose FKBP38 gene was flanked with loxP was constructed by embryo microinjection.The FKBP38 gene was deleted by breeding mice harboring two loxP sites in FKBP38 (FKBP38fl/fl) with the mice bearing the expression ofCre recombinase mice driven by an album promoter.Afterward,the genotype of FKBP38 conditional knockout mice was analyzed.Results:①Relative hepatic FKBP38 mRNA levels showed significant difference between FKBP38 conditional knockout mice (FKBP38-/-) and wild type(P＜ 0.001).②Relative hepatic FKBP38 protein expression levels of FKBP38 conditional knockout mice (FKBP38-/-) were significantly different with wild type(P＜0.001).③Relative phosphorylation of hepatic p70 S6K and 4E-BP-1 protein of FKBP38 conditional knockout mice (FKBP38-/-) showed no significant difference,with slight decrease in phosphorylation of 4E-BP-1,compared with wild type.④No significant difference in expression of hepatic Bcl-2 between FKBP38-/-and wild type.Conclusions:The mouse model of the gene FKBP38 (FK506 binding protein 38) conditional knock out in liver is successfully built.
