Whether or not an abormal expression of IL-6 mRNA in PBMNCs from IDDM patientswas examined using a hihgly sensitive,specific and semiquantitative protocal,i.e.reverse tran-scription and polymerase chain reaction (RT-PCR).The relative levels of IL-6mRNA in PBM-NCs from 12 early IDDMpatients (8.20?3.85yr),29 newly diagnosed NIDDM patients(54.85?9.12yr)23 normal childrens (8.20?3.26yr) and 12 normal adults (31.92?11.22yr)weredetermined.Significantly high expresion levels of IL-6 mRNA were found in PBMNCs from pa-tients with IDDM (P

Objective To study the quality difference of various processing methods about Angelica dahurica. Methods Samples were selected from different places, clean silt by washing and brushing, cut slices and cut blocks in equal division, dried and comminution, to determine total ash, ethanol thermal extract, imperatorin content and HPLC fingerprint similarity. Results The content of total ash was the lowest in “washed”and “washed & cut slice” sample, dilute ethanol thermal extract was the highest in“cut blocks”and“washed&cut blocks”sample, imperatorin content was the highest in“non-washed”and“non-washed & cut slice” sample. Conclusion Washed and cut process is not suitable in place of origin about Angelica dahurica.

Objective To investigate the mRNA and protein expression levels of interferon(IFN)-?in the peripheral blood of patients with systemic lupus erythematosus(SLE),to analyze the relationship between IFN-?and disease activity,and to evaluate the role of IFN-?in the pathogenesis of lupus.Methods SYBR green dyeⅠbased real-time quantatives PCR method was used to compare the mRNA expression levels of IFN-?in the peripheral blood leucocyte of SLE patients and healthy controls.Surum levels of IFN-?were measured with ELISA method.Results IFNA1 mRNA expression level in SLE patients(2.8?3.5)was signifi- cantly lower than that of normal controls(12.7?10.7,P=0.000).There was no significant difference between patients treated with glucocorticoid and those without in the expression level of IFNA1(P=0.549).Serum levels of IFN-?in SLE patients was significantly higher than that of normal controls(P=0.003).The SLEDAI score and anti-dsDNA antibody correlated positively,and complement components C3,C4 and leukocytes correlated negatively with serum concentration of IFN-?.IFN-?level correlated with the presence of fever and rash. Conclusion The close relationship between IFN-?serum level and disease activity in SLE patients suggests that IFN-?might be of importance in the disease process.

OBJECTIVETo determine the role of 1,25(OH)2D3 on the secondary dentin formation and mineralization of the mice.

METHODSThe differences of the mandible mineralization between the wild-type and 1-alpha-hydroxylase gene knockout mice at 6 weeks old were assessed by hematoxylin-eosin (HE) staining, immunohistochemistry, alkaline phosphatase (ALP) histochemistry staining.

RESULTSThe ratio of caries were increased significantly, while the secondary dentin was reduced significantly, the deposition of type I collagen and osteocalcin on the secondary dentin of occlusion surface was decreased significantly, but the deposition of the Biglycan on the dentin was increased significantly, the active of ALP on the odontoblasts were reduced significantly in 1-alpha-hydroxylase gene knockout mice compared to that in the wild-type littermates.

CONCLUSION1,25(OH)2D3 deficiency lead to a defect in the secondary dentin formation and mineralization and caries of the mice.

OBJECTIVETo study modified ilioinguinal approach through the retrospective analysis on the surgical treatment of 63 patients with pelvic and acetabular fractures through anterior approach.

METHODSFrom January 2006 to January 2013, 63 patients with pelvic and acetabular fractures were treated with the ilioinguinal anterior approach, including 45 males and 18 females, ranging in age from 12 to 68 years old, with an average of (37.71 +/- 13.41) years old. All the patients were divided into two groups: standard ilioinguinal anterior approach group (group A) and modified ilioinguinal anterior approach group(group B). In group A, there were 26 males and 11 females, with an average age of (38.49 +/- 13.64) years old. In group B, there were 19 males and 7 females, with an average age of (36.62 +/- 13.29) years old. Intraoperative and postoperative indicators in group A and B were observed and compared, including operation incision exposure time (from skin incision to complete the ilioinguinal in front of three "windows"), the blood loss, incision close time and treatment effect of Majeed function score.

RESULTSCompared to group A, the incision exposure time of patients in group B was shorter, the blood loss (bleeding during exposure process) was less, and the close incision time was shorter, but the treatment effect of Majeed function score had no significant differences between two groups. All the patients were followed up, and the during ranged from 3 to 36 months, with an average of (18.6 +/- 9.2) months. According to Matta standard assessment reduction of pelvic and acetabular fracture, there were 28 patients got an excellent result, 8 good, and 1 fair in the group A; and 20 patients got an excellent result, 5 good, and 1 fair in the group B. According to Majeed function score for hip function, 20 patients got a satisfactory result, 12 good,4 fair and 1 poor in group A, and the mean score was 82.51 +/- 9.72; and 13 patients got an satisfactory result, 10 good, 3 fair and 0 poor in group B, and the mean score was 80.54 +/- 10.79.

CONCLUSIONThe modified approach has several advantages as follows: providing a good surgical exposure; preventing from the injury of femoral nerve, femoral artery and vein under the inguinal ligament; not needing to open the inguinal canal, which can avoid the occurrence of inguinal hernia, reduce operation prodedures and shorten operation time.

OBJECTIVETo investigate the effect of salvianolic acid B (SAB) on the proliferation of human embryonic lung fibroblast MRC-5, and the secretion of procollagen I and endogenous transforming growth factor-beta1, (TGF-beta1).

METHODSThe MRC-5 cells were randomly divided into four groups as follows: the control group: cells cultured with DMEM but with no TGF-beta1, or SAB; the TGF-beta1, group: cell cultured with 10 ng/mL TGF-beta1; the SAB1 group: cell cultured with medium with 10 ng/mL TGF-beta1 and 1 pmol/L SAB; the SAB2 group: cell cultured with medium with 10 ng/mL TGF-beta1, and 10 pmol/L SAB. The proliferation of cells was assayed by MTT incorporation. The concentration of amino-terminal propeptide of type I procollagen (PINP), a marker of collagen synthesis, was measured by radioimmunoassay. The endogenous TGF-beta1, levels were measured using ELISA.

RESULTSThe optical density, procollagen I contents, and endogenous TGF-beta1, levels significantly increased when compared with those of the control group (P<0.05). Compared with the TGF-beta1, group, the optical density was obviously lowered, the procollagen I contents and endogenous TGF-beta1, levels significantly decreased in the SAB1 group and the SAB2 group, and better in the SAB2 group, showing statistical difference (P<0.05).

CONCLUSIONSSAB could inhibit the proliferation of MRC-5 cells induced by TGF-beta1 and attenuate the roles of secreting collagen and endogenous TGF-beta1. It had the potential of postponing or delaying the progressive developing of pulmonary fibrosis.

A comprehensive HPLC-DAD-MS method was developed to study the chemical components of semi-bionic extract of Coptis-Evodia herb couple. The extract was isolated on a Hypersil BDS C18 column (4.6 mm x 200 mm, 5 microm) using acetonitrile-ammonium formic buffer as mobile phase by gradient elution. Detection was performed on DAD and MS equipped with an electrospray ionization (ESI) source by full scan and product full scan on positive mode. The chromatogram of Coptis-Evodia showed seventeen main peaks, eight of which were from Evodia while the others were from Coptis. By comparison of the retention time, the on-line UV spectra and MS spectra, four peaks were identified as jatrorrhizine, hydroxevodiamine, palmatine and berberine, and three peaks were deduced as epiberberine, columbamine and coptisine. In addition, berberine and palmatine were quantitatively determined. No new component was created in the semi-bionic extract of the herb couple, yet the solubilities of berberine and palmatine decreased.
