Serum CA19-9 is one of the markers most frequently detected in the diagnosis and biliopancreatic diseases.The levels of CA19-9 is important for the diagnosis,treatment and prognosis of biliopancreatic diseases.With the development of medical technology,the comprehension of the value of serum CA19-9 is more and more thoroughly.The benign and malignant diseases of biliopancreatic systems can be differentiated by the variation of the values of serum CA19-9,which has high sensitivity in malignant tumors.Serum CA19-9 is one of the independent indicators for evaluation of resectability of tumors and the survival time and life quality of the patients.In this article,the significance of serum CA19-9 in the diagnosis,treatment and prognosis evaluation for biliopancreatic diseases were reviewed.

AIM: To investigate the regulatory effect of the adenosine triphosphate binding cassette transporter A1 (ABCA1) on apolipoprotein E secretion from human THP1 macrophages.METHODS: Differentiation of THP1 macrophages from monocytes was stimulated with phorbol 12-myristate 13-acetate. The macrophages then were incubated with factors which regulate ABCA1 expression. After periods of incubation, apo E secreted in the medium and synthesized in the cell was determined with ELISA, and apo E mRNA espression was detected with Northern blot.RESULTS: An increase in apo E secretion from THP1 macrophages was observed by 8 h of incubation with 8-Br-cAMP, an activator of ABCA1 expression (P

BACKGROUND: Defected Laryngeal cartilage has many alternatives, including autologous cartilage, al ograft cartilage and metal stents. Although these materials can achieve desired outcomes in laryngeal cartilage defect repair, certain limitations exist. OBJECTIVE: To investigate the biocompatibility and properties of artificial ossicular chain reconstruction materials, and to explore the effect of artificial ossicular chain reconstruction materials on laryngeal cartilage defect repair. METHODS: Porous hydroxyapatite otosteon was prepared by high-temperature calcination of hydroxyapatite, fol owed by cultured in bone morphogenetic protein solution extracted from fresh human bone to construct bone morphogenetic protein-hydroxyapatite artificial ossicular chain reconstruction material. And then, the biocompatibility and characteristics of the material were analyzed. Forty adult male New Zealand white rabbits were randomly divided into porous hydroxyapatite group and artificial ossicular chain reconstruction material group (n=20 per group), and underwent repair with porous hydroxyapatite material and bone morphogenetic protein-hydroxyapatite artificial ossicular chain reconstruction material respectively after modeling of laryngeal cartilage defect. RESULTS AND CONCLUSION: There was a significant difference in compressive strength of artificial ossicular chain reconstruction materials with different porosities. No symmetry sphere formed in hol ows of the outer surface of the material, with polygonal appearance and with a pore size of 100-200 μm. There were no obvious adverse reactions in both two groups after implantation, but in the artificial ossicular chain reconstruction material group, numerous fibrous connective tissues and obvious bone nodules appeared, and the degradation rate of the material was faster. These results suggest that the bone morphogenetic protein-hydroxyapatite artificial ossicular chain reconstruction material exhibits good biocompatibility and properties, which wil obtain satisfactory outcomes for laryngeal cartilage defect repair. So, the material holds a great value of clinical application.

To optimize the Scutellaria baicalensis extraction process, the filter paper method and the bacteriostatic ratio method were adopted to determine the in vitro bacteriostatic efficacy of water extracts and 60% alcohol extracts from S. baicalensis. The quantitative analysis of multi-components by single-marker (QAMS) was used to determined the contents of four active components, baicalin, wogonoside, baicalein and wogonin. In addition, with the bacteriostatic ratio and the overall desirability of the contents of four active components as indexes, the orthogonal experiment was adopted to detect the effect of water addition, extraction frequency and extraction time. The optimal extraction process was to add 12 times of water for the first time, 10 times of water for the second time, extract for 2 time, 2 h for each time. This optimization process is stable and feasible, with a higher bacteriostatic ratio in extracts.

AIM: To investigate the quality of life in adults with strabismus and evaluate the improvement in quality of life after treatment.
METHODS: In this prospective study, forty-five adults with a diagnosis of strabismus conform to the inclusion and exclusion standard were selected in our hospital from October 2013 to May 2014, as experimental group and 45 normal adults were enrolled as control group. A Chinese Adult Strabismus-20 questionnaire was used to evaluate the differences of quality of life between patients with strabismus and normal adults, and to evaluate the differences of quality of life in patients with strabismus preoperative and 6mo postoperative.
RESULTS:The scores of quality of life in adult patients with strabismus preoperative and 6mo postoperative were statistically significant lower than those of normal adults (P< 0. 01). In 6mo postoperative, the scores of quality of life statistically significant increased than preoperative ( P<0. 01).
CONCLUSION: Strabismus can decrease the quality of life in psychosocial and visual functional for adults and the surgical treatment can improve quality of life in patients with strabismus.
