Lactic acid production of twelve strains of LAB isolated from broiler intestine and tolerance property of three strains were investigated. The results of lactic acid production showed that among all strains K6 exhibited the most rapid production during the first twelve hours, the seconds were K9 and C1; D17 exhibited the highest production of lactic acid by twenty-four hours, C1 exhibited the highest production of lactic acid by forty-eight hours. The pH values in three strains of K9、D17 and C1 culture showed the fast decline during the first twelve hours, with the final values significantly lower than those of other strains cultures. The results of tolerance property showed that the survival counts of C1could be detected when pH value was at 2 after three hours, but the survival counts of D17 and K9 could not be detected after one hour. When pH value was at 2.5 after three hours ,the survival counts of C1 declined from 10~ 8.2 /mL to 10~ 4.8 /mL, K9 from 10~ 8.2 /mL to 10~ 4.6 /mL, the survival counts of D17 could not be detected. 0.08% bile had few effects on the survival counts of three strains; when incubated in the medium with 0.40% bile, the survival counts of C1 declined from 10~ 8.4 /mL to 10~ 6.5 /mL,D17 from 10~ 10.3 /mL to 10~ 7.5 /mL, and K9 from 10~ 9.8 /mL to 10~ 7.7 /mL. When the group treated with 37℃ for 20 minutes was served as the control, the survival counts of C1 and K9 was not detected when treated with 80℃, but the survival counts of D17 were 10~ 4.9 /mL, when treatment with 65℃ the survival counts of C1 and K9 decreased significantly .

OBJECTIVETo discuss the intervention effect of ligustrazine on ox-LDL-induced foam cells from the perspective of reverse cholesterol transport.

METHODRAW264.7 cultured in vitro was induced with 20 mg x L(-1) ox-LDL to establish the foam cell model, and intervened with ligustrazine. The lipid accumulation in cells was observed by the oil red O dyeing. The changes in total cholesterol and cholesterol ester in the cells were detected with the colorimetric method. The fluorescent quantitative PCR and Western blot were used to detect the mRNA expressions of PPARgamma, LXRalpha and ABCA1.

RESULTLigustrazine could reduce total cholesterol and cholesterol ester in foam cells, inhibit the lipid accumulation, and increase the mRNA and protein expressions of PPARgamma, LXRalpha and ABCA1.

CONCLUSIONLigustrazine can promote the reverse cholesterol transport by increasing the gene expressions of PPARgamma, LXRalpha and ABCA1.

To explore the antagonistic effect of gingerols against the inflammation induced by lectin from Pinellia ternata. In this study, ELISA method was used to determine the effect of different extracts from gingerols on the release of inflammatory factor TNF-α from macrophages induced by lectin from P. ternata. The fluorescence probe was used to determine the effect of gingerols on the changes in ROS of macrophages induced by lectin from P. ternata. The western-blot method was applied to study the effect of gingerols on the increase in expression of cell receptor interacting protein RIP3 in macrophages induced by lectin from P. ternata. The scanning electron microscope (SEM) was used to study the effect of gingerols on morphological changes in macrophages induced by lectin from P. ternata. According to the results, gingerols can significantly inhibit the release of inflammatory factor from macrophages induced by lectin from P. ternata, ROS overproduction and increase in RIP3 expression. SEM results showed that gingerols can inhibit the cytomorphosis and necrocytosis induced by lectin from P. ternata. Fresh ginger's detoxication may be related to gingerols' effects in inhibiing release of inflammatory factor, ROS overproduction and increase in RIP3 expression caused by macrophages induced by lectin from P. ternata, which are mainly inflammatory development.

OBJECTIVETo study immunohistochemical expression of cytokeratin19 (CK19), galectin-3 (Gal-3) and HBME-1 in thyroid lesions and to assess their usefulness as markers in the differential diagnoses of thyroid nodular lesions.

METHODSImmunohistochemical staining was performed on formalin-fixed paraffin-embedded tissue of 21 cases of nodular goiters, 14 cases of toxic goiters, 15 cases of follicular adenomas (FA), 13 cases of follicular carcinomas (FC), 13 cases of follicular variant papillary carcinomas (FVPC) and 48 cases of classic papillary carcinomas (CPC).

RESULTSAll three markers were expressed in the cytoplasm with no or weak expression in benign lesions and diffuse and strong in malignant cases. Positive expressions of CK19, Gal-3 and HBME-1 were present in 11of 21, two of 21, four of 21 in nodular goiters, seven of 14, one of 14, one of 14 in toxic goiters, nine of 15, two of 15, two of 15 in FA, 10 of 13, eight of 13, seven of 13 in FC, 13 of 13, 11 of 13, 12 of 13 in FVPC, and 48 of 48, 45 of 48, 46 of 48 in CPC. The expression rates of the three markers between benign lesions (nodular goiters, toxic goiters and FA) and malignant lesions (FA, FVPC and CPC) were statistically significant. Among the three follicular lesions (FA, FC and FVPC), the differences were statistically significant as well. Nine, seven and six cases were negative for all three markers in nodular goiters, toxic goiters and FA, respectively. Only one case in FC was negative for all three markers, no case was all negative in FVPC and CPC; the rate of one case with two or more positive marker expression in nodular goiters, toxic goiters, FA, FC, FVPC and PC was 14.2% (3/21), 21.43% (3/14), 20.0% (3/15), 69.2% (9/13), 92.3% (12/13), 100.0% (48/48), the differences between benign lesions and malignant lesions and between FA, FC and FVPC were also statistically significant.

CONCLUSIONSImmunohistochemical stains of CK19, Gal-3 and HBME-1, especially when used in combination, can be an important adjunct to the histopathological diagnoses of thyroid lesions.

OBJECTIVETo construct tree models for nasopharyngeal carcinoma (NPC)and explore the oncogenesis process of NPC.

METHODSBased on the software which Desper et al developed, tree models were constructed for colorectal carcinoma (CC) from the comparative genomic hybridization (CGH) data of 118 CC patients and for NPC from the CGH data of 140 southern Chinese patients, respectively.

RESULTSTree models for CC suggested that changes in -18q and +20q were important early events in colorectal carcinogenesis. As changes in -18q occurred prior to those in -17p, there might be some cause-effect relationship. Tree models for NPC suggested that change in -3p was an important early event in nasopharyngeal carcinogenesis, and those in -11q, -14q, -16q, -9p were also non-random genetic events in carcinogenesis, suggesting that there might be tumor-associated genes existing on these chromosome arms. The tree model also suggested the existence of oncogene on the short arm of chromosome 12.

CONCLUSIONConstructing tree models based on the CGH data to demonstrate the initiation and progression of NPC might help elucidate its multigene, multistep and multipathway development. It may provide valuable clues to explore the mechanism of tumorigenesis.

Objectives: Sacral insufficiency fracture (SIF) is not an uncommon osteoporosis fracture among the elderly. Aside from traditional treatments, sacroplasty and teriparatide (TPTD) injection have been introduced. This report aims to compare the effects of sacroplasty and teriparatide on clinical outcomes of SIF. Methods: Thirty-one elderly patients with SIF were enrolled in this retrospective observational study. Four male patients were excluded. Fourteen patients who received TPTD for 6 months were classified into the TPTD group (TT), and 13 who underwent sacroplasty were classified into the sacroplasty group (SS). All patients in both groups were instructed to take calcium and vitamin D supplements daily. Their symptoms and signs, visual analog score (VAS), Oswestry disability index (ODI), and radiographic studies were retrospectively reviewed. Results: The TT group showed significantly lower VAS than SS group after 3 (P < 0.001) and 6 months of treatment (P < 0.001). The TT group also has significant lower ODI than SS group after 1 (P = 0.010), 3 (P = 0.005) and 6 months (P < 0.001) of treatment. Upon generalized estimating equations (GEE) analysis, the TT group showed significantly more reduction in both VAS and ODI compared to the SS group at 1 month (P = 0.022, P = 0.001), 3 months (P < 0.001, P < 0.001), and 6 months (P < 0.001, P < 0.001) post-treatment. Conclusions Postmenoposal woman with SIF who received TPTD healed better than those who underwent sacroplasty after 1 month treatment.

OBJECTIVETo construct a recombinant human CD59 gene containing intercellular adhesion molecule-2 promoter for high level endothelial-specific expression in xenotransplantation.

METHODSICAM-2 promotor fragment and CD59-intron 1 fragment were produced by PCR from the human blood genome, and then clone these fragments into a pcDNA3-CD59 eukaryotic expression vector which was followed by digestion with the specific restricted endonuclease (for example: EcoRI, Hind III). The ICAM-2 promoter and CD59-intron 1 fragments were identified by PCR, and sequencing. The recombinant was then transfected into pig aorta endothelial cells with Lipofection, and the expression was measured by flow cytometer.

RESULTSProducts of the sequences measured were in accord with the frames of the gene bank. The expression of the protein of this recombinant was positive.

CONCLUSIONThe CD59 recombinant gene is constructed successfully, providing a basis for transgenic research.
