Objectives To compare total laparoscopic gastrectomy with intracorporeal hand-sewn Gl reconstruction and laparoscopy-assisted gastrectomy for gastric cancer. Methods Between July 2009 and July 2010, 21 patients of gastric cancer underwent total laparoscopic D2 radical gastrectomy with intracorporeal hand-sewn reconstruction and 28 did laparoscopy-assisted D2 radical gastrectomy in Xijing Hospital of Digestive Diseases. All patients were operated on by an experienced surgeon. Patient demographics, TNM stage, location of tumor, the intraoperative and postoperative details of the two groups were compared. Results In the 21 patients undergoing total laparoscopic gastrectomy, there were 15 of distal gastrectomy and 6 of total gastrectomy, compared with 21 and 7 in laparoscopy-assisted group. In total laparoscopic group, intracorporeal hand-sewn technique was used for gastro-jejunal and jejuno-jejunal (J-J)anastomosis, and 25 mm circular stapler was used for esophago-jejunal anastomosis. The operation time was significant longer in total laparoscopic group than in laparoscopy-assisted group of (279 ± 65 ) min vs.(232 ±40) min (P ＜ 0.05 ). No significant difference was observed between the two groups in proximal margin [(5.7 ± 1.5 )cm vs. (5.1 ± 1.4) cm, P ＞ 0.05] and distal margin [( 3.1 ± 0.9 )cm vs. ( 2.9 ±0.9) cm,P ＞0.05]. The iv narcotic use in laparoscopy-assisted group was 1.8 d but it was not used in total laparoscopic group. The first passing flatus was on day 3 in total laparoscopic group compared with 4.8 d in laparoscopy-assisted group. Both groups had 2 postoperative early complications, one intra-abdominal infection and one lung infection in total laparoscopic group compared with one wound infection and one lung infection in laparoscopy-assisted group. There was no anastomosis-related complications after 4 months of follow-up. Conclusions The operation time and postoperative early complication was acceptable for selected patients treated by total laparoscopic D2 radical gastrectomy with intracorporeal hand-sewn GI tract reconstruction in hands of experienced laparoscopic surgeon.

Plants in Ainsliaea genus, belongs to Compositae family, are traditional Chinese medicine and widely used in folk. These plants contain various types of chemical components, and main components are sesquiterpene lactone and its glycosides. In addition, there are triterpenoids, flavonoids, steroids, phenolic acid, long chain fatty acid and volatile oils. Recently, much attention has been payed to varlous research of A. fragrans. This paper reviewed and summarized the chemical components to provide the theoretical basis for the use of Ainsliaea.

PURPOSE: The objectives of this study were to examine the difference between scores assigned by dementia patients and their caregivers to the patients' anxiety, depression, and quality of life. METHODS: After obtaining Institutional Review Board(IRB) approval, face-to-face interview with the patients and their caregivers respectively was conducted by trained graduate-level nursing students from December 2007 to February 2008. Patients' anxiety, depression, and quality of life were measured by patients and their caregivers. The data obtained were analyzed using the SPSS/WIN 14.0 program, which was used for frequency, percentage, mean , standard deviation, t-test, and Pearson's correlation. RESULTS: Significant relationships were reported between the depression rated by patients and that rated by their caregivers(r = .37, p = .019). In addition, there was no difference between the quality of life rated by patients and that rated by their caregivers(t = -7.11, p = .479). However, there was no significant relationship between the anxiety rated by patients and that rated by their caregivers(r = .21, p = .195). CONCLUSION: There were no differences on level of depression and quality of life of dementia patients measured by dementia patients and caregivers, However, dementia patients' anxiety level has discrepancy between them.

OBJECTIVETo investigate the whole body fat distribution in severe obese patients with multi-slice spiral CT, and to explore the correlation between adipose volume parameters and anthropometric data.

METHODSTotally 14 severe obese patients were enrolled and examined with multi-slice spiral CT. Total adipose tissue (TAT) volume and visceral adipose tissue (VAT) volume were measured using Volume software. The total, subcutaneous, and visceral adipose tissue volumes on umbilical level were also determined. The correlations between these parameters and anthropometric data including body weight, body mass index (BMI), and waist circumference were analyzed.

RESULTSAll scans were performed successfully. TAT was significantly correlated with body weight (r=0.7185ìP =0.004), BMI (r=0.8079ìP=0.004), and waist circumference (r=0.7627, P=0.002). VAT was mildly correlated with body weight (r=0.5727ìP=0.032) and strongly correlated with waist circumference (r=0.6707ìP =0.001). There was highly significant correlation between subcutaneous adipose tissue volume on umbilical level with TAT (r=0.8926ìP=0.000), and mild correlation between visceral adipose tissue volume on umbilical level with VAT (r=0.5949ìP=0.025).

CONCLUSIONSMulti-slice spiral CT can be applied to evaluate whole body fat distribution in severe obese patients. Waist circumference is highly relevant with VAT and therefore can be used as a simple parameter for evaluating adipose tissue inside the abdomen.

OBJECTIVETo explore the possible effect of transforming growth factor-beta(1) (TGF -beta(1)) on the development of renal fibrosis in human mesengial proliferative glomerulonephritis (MsPGN).

METHODSImmunohistochemistry method, sirius red staining polarization microscopy and the computer imaging analysis system were used to detect the expression of TGF-beta(1), the distribution of collagen I, collagen III and collagen IV.

RESULTIn MsPGN with renal fibrosis, collagen IV was increased markedly,and collagen I and collagen III appeared in the expanded mesengial matrix abnormally. Collagen III and collagen IV were increased markedly in tubulointerstitium. TGF-beta(1) expression was positively correlated with the expression of collagen I, collagen III and collagen IV in tubulointerstitium (r=0.82 0.92,P<0.01), and negatively correlated with I/III, I/IV and III/IV (r=-0.83,-0.92, P<0.001).

CONCLUSIONAbnormal increase of TGF-beta(1) may be one of the important factors associated with glomerular sclerosis and tubulointerstitial fibrosis through the increment and abnormal distribution of collagen I, collagen III and collagen IV.

OBJECTIVETo explore the myelo-protection effect of mdr1 transfected cord blood cells (CBMNCs) graft against high-dose homoharringtonine leukemia-bearing severe combined immunodeficient (SCID) mice model.

METHODSMultidrug resistant (mdr1)gene was transferred into CBMNCs by a retrovirus vector, containing full-length cDNA of human mdr1 gene. CBMNCs and high-titer retrovirus supernatant were cocultured with cytokine combinations for 5 - 6 days. The SCID mouse models bearing human HL-60 cell leukemia were divided into three groups. Group A received tail vein injection of 2 x 10(6) mdr1 gene transduced CBMNCs at day 1 and 3, groups B and C 2 x 10(6) un-transduced CBMNCs and same volume of normal saline, respectively. The 3 groups of the mouse model were treated with weekly escalated doses of homoharringtonine. The peripheral white blood cell (WBC) counts, the human leukemia cells percentage in peripheral blood, the histological findings of main organs were assayed. The CD33 positive HL-60 cells in bone marrow were determined by flow cytometry. The function and expression of mdr1 gene were examined by PCR, immunochemistry (IC) and DNR extrusion test in vivo.

RESULTS(1) mdr1 gene was transferred into CBMNCs successfully and the transfection frequency was 30%. (2) Leukemia SCID mice were xenotransplanted with mdr1-transfected BMMNCs by a programmed procedure and could be used as a valuable model for in vivo evaluating myelo-protection effects. (3) The transfected mice could tolerate homoharringtonine 5 approximately 6 folds higher than conventional dose and kept peripheral WBC count at a mean of 3 x 10(9)/L, with the peripheral human myeloid leukemia cells percentage decreasing to less than 5%. Histological examination showed that there was no leukemia infiltration in the main organs, the CD33 positive HL-60 cells in bone marrow were less than 5%. (4) The repopulation frequency of the transfected CBMNs in marrow were 9.13%. DNR extrusion test confirmed that the P-gp product maintained its biological function in the marrow.

CONCLUSIONmdr1 transferred-human CBMNC can xenotransplanted and repopulated in leukemia-bearing SCID mouse and are protected from chemotherapy-induced myelosuppression.
