Objective To investigate the quality assurance (QA) and quality control (QC)of intravenous injection in the radiology department. Methods The data from 1352 cases of intravenous injection in the radiology department were analyzed retrospectively. Results The bulge in region of the intravenous injection have been found in 28 cases, regional cyanochroia in 52 cases, allergic response in 25 cases, hypoglycemia response in 58 cases. Conclusion It is important to strengthen the QA and QC of intravenous injection in the radiology department.

Objective To investigate the infection of human papilloma virus(HPV) and expression of serum squamous cell antigen (SCCAg) in the follow - up of 120 cervical squamous carcinoma patients who had received operation or operation combined with radiotherapy or only radiotherapy. Methods 120 cases of therapical cervical squamous carcinoma patients were detected HPV - DNA by HC - Ⅱ and serum SCCAg using immunohistochemical method. Results The positive rate of HPV - DNA and serum SCCAg was 49.17% and 17.50% , with a significant difference between them( P 0.05 ). Conclusion HPV - DNA test with HC - Ⅱ for follow - up of cervical squamous carcinoma patients was feasible. It was more sensitive than serum SCCAg. But it suggested that high risk type HPV -DNA test combined with serum SCCAg may be the independent prognostic factors.

Objective: To evaluate the expression of galectin-3(Gal-3) in cervical cancer tissues and its correlation with clinicopathological and survival variables. Methods: One hundred and seventy-four patients with International Federation of Gynaecology and Obstetrics (FIGO) stage I/II cervical carcinoma undergoing radical surgery were selected, and their cervical cancer tissues were collected. The expression of Gal-3 protein in cancer tissues was semi-quantitatively tested by tissue microarray and immunohistochemical analysis. Then the correlations of the expression of Gal-3 with the clinicopathological parameters, treatment outcomes and the survival of these patients were evaluated. Results: The positive expression rate of Gal-3 was 54.0% (94/ 174) in the cervical cancer tissues. In a univariate analysis, the positive expression of Gal-3 was closely correlated with non-squamous cell carcinoma (P=0.006), lymph vascular-space invasion (LVSI, P=0.048), deep-muscle invasion ( P= 0.001) and pelvic lymph-node metastasis (P<0.001). The multivariate analysis revealed that the expression of Gal-3 was one of the independent risk factors for predicting pelvic lymph-node metastasis. The risk factors including FIGO stage II (P<0.001), LVSI ( P=0.013), positive parametrium invasion (P=0.015), pelvic lymph-node metastasis (P<0.001) and the positive expression of Gal-3 (P=0.013) were significantly correlated with poor overall survival in these patients with cervical cancer. The tumor remission rate was lower in patients with up-regulated expression of Gal-3 (39.7%) than that in patients with down-regulated or invariant expression of Gal-3 (70.0%) after receiving preoperative radiotherapy. Conclusion: Positive expression of Gal-3 protein is a predictive factor for pelvic lymph node metastasis and worse overall survival in patients with cervical cancer. Up-regulated expression of Gal-3 protein may be associated with the resistance to radiotherapy.

This study aims to explore the inferior adhesion of the renal fascia (RF), and the inferior connectivity of the perirenal spaces (PS) with multidetector computed tomography (MDCT), and to investigate the diagnostic value of CT for showing this anatomy. From May to July 2012, eighty-two patients with acute pancreatitis presented in our hospital were enrolled into this study and underwent contrast-enhanced CT scans. All the image data were used to perform three dimensional reconstruction to show the inferior attachment of RF and the inferior connectivity of PS. The fusion of anterior renal fascia (ARF) and posterior renal fascia (PRF) next to the plane of iliac fossa were found on the left in 71.95% (59/82) cases, and on the right in 75.61% (62/82). In these cases, bilateral perirenal spaces, and anterior and posterior pararenal spaces were not found to be connected with each other. No fusion of ARF and PRF below the level of bilateral kidneys occurred on the left side in 28.05% (23/82) cases and on the right side in 24.39% (20/82). In these patients, the PS extended to the extraperitoneal space of the pelvic cavity and further to the inguinal region, and bilateral anterior and posterior pararenal spaces were not found to be connected with each other. Three-dimensional reconstruction on contrast-enhanced MDCT could be a valuable procedure for depicting inferior attachment of RF, and the inferior connectivity of PS.

Objective To investigate the effects of transforming growth factorβ1(TGFβ1)and β3 (TGFβ3)gene transfer on MMP-2,MMP-9 and TIMP-1 expression in hepatic stellate cells(HSC-T6).Methods TGFβ1 and TGFβ3 expression plagmids were constructed.The recombinant expression plasmid pcDNA3.1(+)-=TGFβ1 and pcDNA3.1(+).TGFβ3 were transfected or cotransfected into HSC-T6.At 24,48 and 72 h after transfection,the expression of MMP-2,MMP-9 and TIMP-1 mRNA were detected by real-time quantitative PCR,and the expression of MMP-2,MMP-9 and TIMP-1 protein were detected by Western blot.The recombinant expression plasmid pcDNA3.1(+).TGFβ1 was transfected into HSC-T6,and positive clones were selected by G418.The positive clones were transfected by the recombinant expression plasmid pcDNA3.1(+).TGFβ1,and the expression of MMP-2,MMP-9 and TIMP-1 were detected at 48 h after transfection.Results After transfection with peDNA3.1-TGFβ1,MMP-2 and TIMP-1 increaged remarkably in HSC-T6 cells(P＜0.05),but MMP-9 remained at the sanle level;After transfection with pcDNA3.1-TGFβ3,expression levels of MMP-2,MMP-9 and TIMP-1 mRNA were not changed,but TIMP-1 protein increased remarkably(P＜0.05);in cotransfection group,the expression of MMP-2 was higher than that in the blank and the control groups(P＜0.05),but MMP-9 level was not changed and TIMP-1was decreased compared with that in the TGF-β1 transfection group(P＜0.05).After TGFβ3was transfected into positive clones,the change of MMP-2 wag not significant(P＞0.05).but MMP-9 increaged and TIMP-1 decreased significantly at 48 h after transfection(P＜0.05).Conclusions TGFB3 may inhibit liver fibrosis by increase the activity of MMP-2 and MMP-9,and decrease the activity of TIMP-1.

The energy expenditure in the late stage of pregnancy was studied. The workers of three kinds including spinner, sewers and kindergartners were selected, and ten healthy pregnant women were matched to non-pregnant as subjects. Energy consumption was measured by indirect method and calculated from dietary survey. The results showed that the energy expenditure for spinner, sewer and kindergartner in pregnancy was 9.5474, 10.1253 and 8.7287 MJ/day, but for non-pregnant woman was 9.4453 10.1281 and 8.1567 MJ/day respectively. Calorie intake was 10.8910, 11.2424 and 9.9830 MJ/day for pregnant women, but 9.2215, 10.4474 and 8.6734 MJ/ day for the non-pregnant women respectively. The difference of energy consumptions between the pregnant and non-pregnant women was not significant, but the calorie intake for the pregnant women was signigicantly higher (0.8368 MJ/day) than the non-pregnant. According to the energy consumption, we recommend the calorie intakes in the late stage of pregnancy may increase 0.8368 MJ/day.

Objective To investigate the experiment effects of rabbit joint articular cartilage defects repaired by thermosensitive CS/PVA composite hydrogel engineered hTGF-β1 transfected bone marrow mesenchymal stem cells. Methods Bone marrow mesenchymal stem cells were isolated and cultured in vitro. The positive rate of transfection was defected by cell immunohistochemistry methods after Ad-hTGF-β1 transfected for 1 week. Twenty-four adult New Zealand white rabbits with full articular cartilage defects were randomly divided into 4 groups, each group had 6 animals, both hind limbs were used in the experiment. Group A: hydrogel combined with transfected cells; Group B: hydrogel combined with untransfected cells; Group C: hydrogel group; Group D: blank control group. Specimens and histological observation were used to evaluate the repair effect after 16 weeks according to Pineda's score. Results The positive rate of hTGF-β1 expression in BMSCs was about 85.4% after transfection. After 16 weeks the defects of group A were repaired by cartilage-like tissue, the cell arrangement and densities of regenerated cartilage were similar to normal cartilage, type Ⅱ collagen immunohistochemistry were positive. There was a significant difference in Pineda's score compaired with other groups (P ＜ 0.05). Conclusion Rabbit articiular cartilage defects could be repaired by CS/PVA hydrogel engineered hTGF-β1-transfected bone marrow mesenchymal stem cells.
